Yesterday, the server host disabled the site since it was using an excess amount of database resources. Since the resources are shared with other sites on the server, this caused problems for others, and they determined that the problems went away when our site was disabled.
For now, they've enabled the site again, but asked that the forums be disabled until we can find a more resource-friendly solution (or if we upgrade to a virtual private server). Since we don't have the budget to do VPS (at least here), we are investigating what we can change.
For now, this means that all forums are temporarily disabled and no new forums will be created. The main site will remain online in the interim, so feel free to discuss on the forums. (We switched the current built-in chat to the previous IRC option to also keep database usage down.)
