I don't really know the best way to explain this but it's been happening on and off for ages now -
In the 'Other Football' forum I often can't read new posts in a thread for a few hours after they've been posted. It seems to only happen when someone's made the first post on a new page, and especially if it's me (maybe even every time it's me). It's happening at the moment with the CL thread - the forum keeps telling me that someone else has made a new post (Last post: Clrnc @ 2:23) but if I click on it it the last one I can read is Kurtz's from last night.
It's not a big deal but because it's happened so regularly for so long I thought I should mention it at last Pepe. It only seems to happen in that forum too, odd.
