Thats cool ^^
Well as far as rules.. well I cant think of any that arent the usual "Be nice to others and dont steal artwork"
Basicly be a nice person and you are fine
I believe you have to be 14 or older to sign up aswell so swearing is fine so long as it isnt used in an excessive and or offensive manner aswell.
I am sure you will have lots of fun here! There is so much to do, from chat rooms to message board to help find any potential job offerings. Also groups to help get your name out there and meet others that are also experienced in your area of work. For the most part people are really nice here too and understanding, but like anywhere else there is always that one person that has signed up just to be rude, nasty and just ruin someones day.
