Rascal~

To make a character, add their profile page in the Character Database. From there, you now have a link to your character's profile page, with this link you can sign up to roleplays. 
You go to the OOC Discussion to sign up, plan, search, and create your own roleplay ideas. When you have signed up for a roleplay, or have created one yourself, you can either place the roleplay thread in the Normal Section or the Advanced Section. The Normal has only a 200 character limit to make a post, while Advanced has an 800 limit. 

Though of course, these forums also have a special roleplay section. In the Equestrian Empire Section you play in more cannon world, where lore is fixed and main cannon characters also have a fixed user signed to them to play in roleplays. 
I suggest that you read all the topics that are pinned here, and this Guide to Roleplaying first, before you read the Equestrian Empire Roleplaying Rules and How to join Guide and then have a read of all the topics pinned in the Equestrian Empire OOC Discussion section. 
Once you've had a read, and hopefully understand all the info you've just sunken in. You can make a character in the Unapproved Character section of the Equestrian Empire Character Database, when your character has been approved it will be moved to the Approved Character section, and then you can use your original character or cannon character in the Equestrian Empire Section. 

Of course, the Equestrian Empire may not be for you, so just stick with the first paragraph and read all the topics pinned here. 

For the member title you cannot change it unless you donate or subscribe to the forums, doing that allows you to  change your member title, bigger signature space and avatars, your name in gold, and some other things as well. 

For cussing, keep it minimal. Don't swear in every sentence or second word and mostly keep your posts clean
