Art Cabin now offers you not only a listing with a web link, but also the ability to display and sell your artwork online in this really user friendly website for only £12.95 a year, and you can log in and make changes to your portfolio whenever you wish.
It also allows you to add articles and blog entries to the new article directory, so well worth a look.
The Art Cabin website can be seen here http://www.artcabin.net
