I think having a separate section for Tiles request will be nice. Not all are good in making stunning tiles which replace the default ones. Those who are good with graphics can give a helping hand.
While I semi-agree with this, I think at least some guidelines on what makes a good tile, since they resize. Ive tried a few and most have failed to look good.
@kelso I guess that will vary from person to person. Users can describe what exactly they are looking for (or at least give an idea, like related to niche).
