Once your character has been accepted, you can finally start posting in the RP forums! Here are some guidelines on what you need to have in all of these posts. *Note that you may have multiple threads open at once.
The first thing to do when you post is decide if it will be STARTER, OPEN, INVITE, MOD, CLOSED, or ONE-SHOT.
A STARTER topic is simply your first RP post in the Emissary, Lab, or Market. These are only there to catch the eye of the Starter Topic mods.
An OPEN topic is one that anyone may join with no limitations. However, if you plan to be absent for a time, let whomever you've jumped in the thread with know so they can plan accordingly. OPEN threads have a 300 word count minimum so that the monetary system isn't abused.
INVITE topics are created to RP with a specific person or multiple people, and the "INVITE" is replaced with their name(s). For instance, if Jasper wants to RP with Morgan, a thread might be titled "A Day Out [Morgan]". INVITE threads have a 300 word count minimum so that the monetary system isn't abused.
A MODDED topic is an interaction between the player and a staff member. You don't always need a Mod to play the world for you, but if you want to use them for whatever reason, I encourage you to do so! Most often, Mods will spawn Pokemon and NPCs and control those.
CLOSED topics are similar to Modded ones, except that the player is allowed to control the things the mods spawn. For instance, in a Modded thread, if a Wild Pikachu appears, the player posts, then the Mod posts as Pikachu, then the player, then the mod, back and forth. Modded threads can be very dynamic, but often incur a wait time. In a CLOSED thread, a mod can be called in to spawn (a) wild Pokemon, and then the player can control both his or her own Pokemon and the wild one(s). When the battle is over, a Mod should again be called in to review the battle (or whatever you overcame) and award experience or other rewards if it is found acceptable. These threads can also be used for taming Ferals, training Abilities, and more.
Word Count for this type of thread is 500 minimum. You may only have one Closed thread per character at a time and may only post 1/day.
ONE-SHOT topics are exactly what it says on the tin. You make one long post, no mods, no nothing. These can be used for exposition or reflecting on past events or just 'hanging out' with your Pokemon without trying to train/tame them, etc. There is no special benefit to them other than the normal money for making a post, it's just fun. Word Count for this type is 500 minimum. You may only post one One-Shot per character per week. The EXCEPTION to both of these requirements is one-shot threads quickly passing through areas through which a character has traveled before. These can be done as often as necessary and don't have a strict word count; a few sentences will suffice, though feel free to do a lot more. Note that running around the whole world just to make more mini-threads is not 'as often as necessary'.
Body & Signature
As stated before, there is no word count for any topics other than CLOSED and ONE-SHOT threads, however, it is considered courteous to always give your Mod, partner, or whomever enough to work with. Do your best to avoid dead-end posts. Ask yourself, "are there multiple ways to react to this?" and if no, try something a little different. And remember, Quality always trumps Quantity.
Now, on the first post you make of any thread you need to let everyone else know what time of day it is, the day/month/year, your specific location, the weather, and temperature. The first post lays out the setting of the thread, so it's very important that all of this information is somewhere in the post. The time/date can also be timestamped above the body if you'd prefer. Individuals should post their party Pokemon's level and status (conditions and Feral/Tamed) when they first enter a thread to avoid conflicts with other posts.
You may have noticed from reading the Character page that there are lots of Perks to deal with. For instance, Mercenaries receive a 10% bonus to experience, Barters earn more coin/post. Because of all these benefits, it's very difficult for mods to remember to grant you all of your bonuses from our own memory. Therefore, it is asked that in every post, in your Signature (or somewhere in your post code if you'd prefer) you have the following things:
Active Skill Perks
Active Skill "you need this many to get this" entities
