Thanks Jeff!
The biggest new "feature" is stability and performance. This was a complete rewrite using ASP.NET MVC and SQL Server 2008 R2 instead of the old ASP and an Access database. So, we should scale much better now. Hopefully the site feels faster to you as a result.
Some of the side benefits of the new site currently are that our URLs will be more "searchable", so hopefully that helps more people find our community.
Some minor improvements include CAPTCHA for posting comments and forum posts for your first 10 posts, so hopefully that will cut down on SPAM - something I know you're passionate about stopping ;).
In the not-too-distant future, I plan to add more features to allow content posted by site members: articles, links, files, photos, etc. I'm also planning some special features for performing thereminists... but more on that later :)
The highest priority right now is completing the porting of all the old content from the old platform to this one. As soon as that's done, I'll get started on the new features.
If you have any suggestions for features or find any bugs, please keep the feedback coming.
thanks!
Jason
