I can definitely say we're still open. There's not really a "maximum cast size" that I know of.
So, as long as you can throw together a character that will pass muster, you should easily be able to hop on the chaos train.

Currently, we're in the waning stages of wrapping up the trio of "intro Arcs" (some being rather further along than others *cough*Ot Herap Yo*cough*), so you'll likely be sliding in either during the last bits of the "Midnight Tounament" arc that's about to go batshit or during the start of the next arc. Admittedly, Midnight is also extremely crowded in terms of PCs already though, so it may not be the best fit.
