Does anyone know the size the emblem for the clan logo has to be? and how to do you upload it as well?

150x150?

Just paint one with the grid on 32x32 grid, well it may be harder than just painting one if you are not artistic.

I think he's talking about making on in like photoshop and then uploading it (Could be wrong tho' If so, then I'm wrong.. Obviously :P)
But I myself am wondering about that being possible? If not then I'll just keep making them in the game. It's not that hard when you have been doing pixleart for years.
