First: comtitle wy=[ansi([pickrand(color-code color-code etc.)],[u(pickrand(lattr(%#/channelalias-*)))])] - Color-code = ansi code & channelalias=your alias for that channel.
Example: comtitle wy=[ansi([pickrand(hx hw hr r)],[u(pickrand(lattr(%#/wycomtitle-*)))])] - This would pick between Gloom, White, highlighted red, and red. And it would only select from &wycomtitle attributes.
Then add your code: &channelalias-number me=Witty thing
example &wycomtitle-1 me=It's Yeet or be Yeeten! *Name (*optional for anonymous channels)
