Help Community Board (ALT+B)

[sorryformyenglish]

Hello guys! need some info/help :) how to edit community board? program? pack side files? client side files?

Download a random community board created by someone else and read the code of it to understand how it works, or take a look at retail cb from game inside your pack's html folder. Client wise, you need to add textures (.utx) and call them in your html code.
