I didnt know this either.
I was playing with the idea of renaming my club to something more catchy and was wondering if it was even possible. But now that im reading all the disadvantages to this idea...im thinking, naww...im good. LOL
Ive changed clubhouse names twice (once was due to a typo error) and after booting thr members and deleting I was able to recreate a new club. BUT...this was 3 months ago, so things hay have changed recently.
