Actually we r using ver 2.8.6 (WPmu)
We now have so many blogs that they list over 1 pg. I just added 5 blogs, the 1st few appeared OK, but I couldn't c the others. Thought I skipped 'em, so I tried 2 add again. WP said blog already exists. After doing some other task and then coming back, I noticed some buttons on top of the page saying 2, next. So I was able 2 get 2 the next page of blogs - Hooray! However the same button weren't at the bottom of the pg - like other lists on WP.
Perhaps this has been fixed on later versions - we haven't upgraded yet.
