These are the only 6.5.2 forums I know of at the moment...as all other sites I requent have stayed away from it thus far.
I come here and the lightbulb is lit. So I click the forum to read the new messages.
None of the messages in that forum are highlighted, bolded, yellow-imaged, or otherwise standing out from any others.
I have tried "Mark All Read" - and I have tried deleting my cookies and starting here fresh. Neither has worked.
So FYI it appears 6.5.2 still did not fix Post Tracking.
