Like Isketch? But never liked the point system? Don't like the fact you have to draw what the words mean, or that only one person (technically two if you pick tandem mode....) can draw at a time? Just want to go batshit insane and draw whatever you feel like?
Well try Iscribble. But you have to make an account...and read the bottom.
NOTE: DO NOT MAKE A PUBLIC BOARD. EVER. YOU'LL GET BANNED! Or at least you will if you draw and type inappropriate content....
Just make a private board, and start inviting people when they say they're going to join.
For those that start boards: When a person who wants to join says his SESSION name, you type /invite (insert person's SESSION name) and he'll be invited to join.
For those that want to join boards: When you want to join, type your SESSION NAME (NOT ACCOUNT NAME) so the person that did start the current Newgrounds board can invite you.
Board is up, just tell me your SESSION name (your session name is the name you get when you log in, though usually its your account name, though some people decide to pick different session names.
This is getting complicated isn't it?
