Yea, this may sounds pretty pathetic, but I need to know how to add/remove someone to your clan.
I rescently became the owner of [coffee] clan and I need to know how to add/remove members.

If you go to "Clans" at the top of the page it should take you to your clan's homepage or whatever.

If yous scroll down it will say "kick User" and you can select whoever you want.

I think the problem is that you have the "leader" as the lowest rank. You need to be at the top.
