I know, nobody reads this - but - i´ll give it a try.

Just restarting a small project and maybe someone has an Idea what to add, which features whould be good to have.. etc.

It is easy. The ArtTracker is a place where artists can show and update their lists of comissions, gifts, trades,collabs etc. Each comission can have its own page for collecting references, or any other information conecerning. It can be private or public. It simplifys the way keep track of your works, and you decide whether the public is allowed to see it.
You can easly create own pages to show your pricing, or what you do/dont draw. There is a internal messaging-system, too.

Everyone can make his own profile with informations, pictures, references concering his/her characters.

Designs are changeable via CSS so individual pages are no problem.

Please write me any ideas, or just comment what you think about it.
