I have a few posts that use "." (period) in the subject line.
The interesting part is that some work just fine like this one: http://gmatclub.com/forum/12-31-divisib ... 55942.html
But others don't like this one: http://gmatclub.com/forum/12.28-56238.html (you will get not found error if you click it but it exists - I can see it from the forum listing page here: http://gmatclub.com/forum/gmat-math-que ... -7260.html or here: http://gmatclub.com/forum/gmat-math-que ... -7290.html (if there are more posts, then pages may have shifted. You may want to look at the next page)
So far I have found only 3 posts like these on my forum with 60K+ pages. I can get into the post using a moderator control panel but that's the only way I can view them. I tried changing the title of the first post but that did not help. Any suggestions - i am happy to change them manually if needs to be done.
Any suggestions?
