Hmm…I’ve never heard anything like mini PR update before. Are you sure it wasn’t a glitch. Did you confirm using other online PR tools?
I have never heard of a mini PR update either but something obviously happened because your pr increased.
May be you have excluded www of your forum previously. PR is different for http://www.xxxxx.com and http://xxxxx.com
I always heard PR downgrade when PR update takes place other than normal PR update after 3 months. But your PR went up. Strange
Is it a sub domain, or a site that has been pr0 for awhile this is very interesting would love to hear more about this?
lol...just logged in here to see if there's been any pr updates and i found this thread, yeah same thing happened to me...i just noticed that one of my sites changed from 3 to 5 in the last few days really happy about that..
this is interesting, never seen anything like that before, now you got all of us checking every one of our sites
