I'm in the process of upgrading to new blogengine.net version, and in that process there might be some issues while I get it all set up.
I'm also going to clean up the comment spam pretty heftily - so in case your legit comment vanishes, I'm sorry in advanced, but I just had to prune some 3000 spam comments
I'll also look at incorporate a catpcha as well as automated spam detection built into the engine, so hopefully comment spam and moderation of them will be easier.
And finally - I'm going to try out feedburner for my RSS feed, so I hope I do not break anything by it :)
Thanks for your patience.
