Having problem with sense ??
Why don't you just say "Ok I'm new leader of H4L, sense is nomore in the clan" and all H4L members can confirm.
OpenArena is a democratie.
I like democratical clans, so I can support you.
If all H4L members prefere to have you as leader instead of sense, I don't see any problem with that. He just ruined a good clan, he expelled all principal members and closed the clan. It's lame, that's why I think you can just be new H4L leader, if your members follow you, you can open new website.
A leader is not just the guy who claims "I'm the leader, I'm the best, I'm the master", the leader is the guy who others follow If people prefere to follow you instead of sense, I repeat, you will not have any problem
