As the community was warned about in advance several months ago, the old Marketplace forums should now be closed to further posting, and all further marketplace activity should take place within the group. A sticky has been posted in each of the old forums to direct posters to the group. If you find someone asking about what happened to the marketplace, please let them know about the move and send them our way.
The information from the various old forum stickies has been retained and will be reformatted, consolidated, and reposted at some as-yet-indeterminate point in the future--when exactly that is will depend on how much spare time can be devoted to the conversion. If you would like to help with this process, please send me a PM and we'll see what we can work out.
For those of you just now reaching us, a detailed explanation of why the Marketplace has been moved can be found here.
