I posted yesterday that we had upgraded to the current version of BE 2.9. We, as you might expect, had a few minor issues, but I must say the support on the discussion forums has been excellent.

This included the problems I had that were down to missing files and web.config issues (basically my copy errors when moving content from our BE 2.8 instance to the new BE 2.9 on) and a genuine bug in the new CustomFields code (fixed in 2.9.0.3). All discussion posts were responded to, and in the case of the bug fix, within a very short period of time.

If you need a blog server and have not looked at at BlogEngine.NET I think it will be well worth your time taking a peek
