There seems to be a problem over the weekends when no maintenance is taking place. Something obviously builds up and gums up the works preventing access to older pages and also to ones own threads uder the user-profile.
Come Monday, the buffers are generally cleared and all is well again, which is fortunate since I had to find my way back there this morning to score the KM Links game in the absence of seekeerz
Hopefully you will find things are OK now - - - until next Sunday.
