Numista is being incrementally improved all the time - though I admit that the improvement had slowed down somewhat lately.
I began submitting items over the weekend. The moderator for Lorraine was very responsive, so I'll be adding some things there (maybe 10 new types) over the next few weeks.
For another area, I have no response yet for the 4 coins I submitted.
Really the big problem in Numista coverage improvement is their relatively stringent rules on image copyright (as should be expected, since anything else would be a huge legal problem, but it does make finding usable images rather tricky).
I got around that by using my own images, but I understand the point. It seems that some contributors have gotten permission from auction houses to use their images (for instance, I see photo credits given to Jean Elsen for some images of Brabant coins).
