Ok, now that my hands have been untied, I can help you! To answer your question: Yes, you must ask permission by a Clan Mod to start a tourney in the Clan Arena (and make sure to have a mini-message at the top of your new thread saying "Approved by [Insert Mod's Name Here]"). If you want my opinion, I'd ask
Cambria permission (and if I were you, I'd PM her your whole introduction to your tourny. Remember to list all the rules, registration requirements, etc...like I did in
my old thread).
