Quoted from TomDK:My "topics activity" is killed .... seems that something wrent wrong today.
Also all markings about read topics and forums are gone ....
I found the same when i checked. However, when i turned off "Hide Idle" it showed all the topics i had posted in *with* the markings. So it seems it may be in a transitional state or we just need to bring it to Robin's attention to get it fixed up.
