you can find them
here. Use these in role-play posts. They are quite convinient when it comes to the issue of logging in and out again and again just so that the proper character goes to the proper story. We do request that you not do it all the time though.
If you apply for a new character don't worry about the tag until a week after your character has been accepted. If it hasn't been created then notify an Admin so that they can have one made. If you do not understand how the tag is used message lady isolde(myself) and she'll help you understand it a little more.
