Kayhynn was asking me for XenForo advance recently. I guess she sets up communities for clients, but apparently isn't familiar with XF. Maybe she'd buy it.

Buy a goofy domain like spamcentral.com or something and let it grow like a weed and see what happens. A little experiment if you will. No spam controls, guest are allowed to post, etc. Let it all hang out. If you don't, I might just to see what happens.
