Once you\'ve got your profile posted, someone such as our good friends Satyr or Existentially Odd comes bad and approves it, or helps you improve it, from there you can start a roleplay anywhere you think appropriate, and then advertise it in the "new roleplay" section. Once you\'ve done that people will flock to your post... sometimes... and then you go from there.
Some roleplays can be for one other person only, or more than one person. Depends on what you want. ^.^
Hope that helps.
