Regarding the New Banner Format...

[DND 2,354]

I've noticed that MLPForum's banner-making guidelines have not been updated. Being a person that likes to make graphics, I wanted to try another shot at making banners, but I don't know the new format. 

 

Is this privilege exclusive now? If so, why?

The banner making guidelines will be updated as soon as possible. It appears as if this was just an oversight. 
Sorry about the wait on this answer, It shall be attended to as soon as possible
