Hopefully you should not notice, but we have moved this Blog Server from using Community Server 2007 to BlogEngine.NET. We have been busy bring over all the content so any search should still return the same page, but it might take a few days.
I will be posting on my experiences as soon as I have my notes sorted.
THE MAIN CHANGE YOU MIGHT SEE IS THAT THE BM-BLOGGERS AGGREGRATE FEED HAS MOVED TO http://blogs.blackmarble.co.uk/blogs/syndication.axd
