DM's are expected to post their quests in the game recruiting board IC, to include a brief description of the outline and homebrew content if the world is not a premade setting. You may also wish to entice the PC's with the promise of a reward such as a magical item from the quest giver if they complete the quest. You must also post a spoiler tag that lists the following data:
Thread Title:Include number of players and level requested as well as the room number you expect to use.
Title: Name your ad something memorable that conveys a great idea about the type of campaign or adventure you wish to run.

Use of a picture is always recommended.
Theme Music Link: Linking to a nice song on youtube can help set the stage for the mood you are trying to set for the players.
Posting Requirement: How many times a day, week or month are your players expected to post? If your game is already running, mention that, and take the time to realize adding another player may change the pace to become faster or slower depending on how the PC interacts. This requirement should be the MINIMUM requirement to post without some sort of prior notification. This range will vary drastically from game to game and is dependent upon a multitude of factors. As a general rule, requesting players post more than once a day can quickly become problematic. In some cases you may wish to also add a maximum posting rate such as "no more than three posts from a player before the DM and/or all respond at least once" to make sure that everyone has a chance to respond appropriately.
Generally, the suggested rate is 5-10 posts per PC and GM per week, but variances are allowed at GM discretion so long as they are written in here and XP variance is modified.
Level of adventure and estimated rewards: What level range should applicants be? Keep level range tight, no more than a 1 level spread (+/- 1 level) with a target of zero level spread (all level spreads greater than zero and under level 10 must be approved by the Head GM). Larger spreads are not allowed because they create game balance issues. Give an estimate of roughly how much XP will likely be earned from this adventure. Standard Adventures are worth 100 xp with shorter adventures being worth less and longer adventures being worth more but never more than 200xp. The 100 xp reward is based on a standard real time 3 month long adventure with an average of 5-10 posts weekly per player and GM. More or less may be given based on PC completion of objectives, potential RP bonuses and adventure length, all factors of which are subject to GM discretion. Generally speaking 100xp is the norm for levels 1-11 with a rough range of 50-200 depending upon adventure length. Once level 12 is achieved, PCs receive modifiers for xp gained in adventures.
Requesting "x" players: How many players do you need? Keep in mind that the larger a group becomes, the greater the chances someone will hold up posting by being absent. Play by Post games with over 10 participants in them exist, but they are the exception and not the rule. Generally at Eternity's End games are targeted at 3-5 players though smaller groups and solo missions exist. Generally speaking, having more than 5 players is not recommended but not against the rules.
Special Restrictions/Requirements: such as No spellcasters, Elves only, etc. If the party needs a particular class asset (such as: "must have a healer"), mention that here. Never put players into an adventure they have no hope of succeeding in unless it is strictly a survival type game, at which point you should emphasize that fact in the advert. Generally speaking, limiting your options like this as a GM is suggested against but not prohibited.
Setting: If you have a specific pre-made campaign setting you are using, post it here, otherwise list as "home brew". Include optional data like "will be on the plane of fire" or "will take place in the underdark" or "adventure not suiting to mounted characters" or whatever if you think it's important to the players and would like to let them know.
Flavor Text: Include your IC description here. You may start your IC description in the pub, but it is recommended that you always have PCs apply to the adventure outside of the pub, usually in the room number itself, just outside the door, in the hallways, or some other location that does not contain a static NPC that can be interacted with. This is to prevent issues with timestream continuity.
To rectify any discontinuity players are encouraged to carry out IC actions as specified. For example, if an adventure is posted on a corkboard in the pub, the character is encouraged to look at the cork board IC in the pub and then leave off in search of the room or other location and then apply IC in the Advert when they are ready to join.
