Hi Chuck,
The issue you're facing is almost identical to the issue David was facing yesterday. I just checked and the solution I suggested for his problem should work for you too. You'll just need to change EntryID to BlogID.
You can follow the link above for details and a link to a video where I showed how to implement the change, but basically, you just add an entry to the Friendly URLs in Host Settings. You'll need to make sure the entry you add is above the default DNN entry which has a match that looks like this: [^?]*/TabId/(\d+)(.*) . You can do this by following the method I showed in the video or by editing the siteUrls.config file directly. Your Match and Replace With values would look like this:
Match: [^?]*/TabId/36/BlogID/(\d+)(.*)
Replace Wtih: ~/Default.aspx?TabId=56&BlogID=$1
Again, you'll want to make sure this entry appears before this entry [^?]*/TabId/(\d+)(.*). If you don't, your match will be ignored.
HTH,
Don
