A forum!
Your clan must have a forum after a week when you posted or it will get deleted. +the forum must be nicely coded (not just adding the categories, but changing the theme, HTML the site).
If you can't code a forum then you need someone else to do it for you. I'm most of the time free so hit me up in-game or PM me on forum if you need help to code one, or can't make one.
