Applying/Getting Gm.... twice
Also winning Fish's tourney to get meh kewl green hat.
The clans I've been in were great ([Addicted] [u] and now (im) to name a few.).
The best thing I've done, by far, was making a clan with Ele and some other p awesome guys. It was a good thing it happend or I'd not be nearly as active as I have been. Plus, it was a whole lot of fun iirc at the time.
