You'll also notice that the search feature, especially for Discussions and Q&A, is not as good as it once was. In fact, I don't think it works anymore at all. I used to be able to search for certain subjects or keywords, but not anymore. For example, do a search for a past discussion with a known title, and it won't be found. (At least it hasn't worked for the ones I've searched for.)
There's also been a change in the list of Q&A and Discussions a member has participated in. In the past, I could have reviewed all of them, or perhaps most of them, by clicking on the member ID and following the "Q&As Participated in" link, but now it's limited to the twenty with the most recent activity. For example, look at the discussions or Q&A the you've participated in, and you see a list of twenty. There used to be an additional link to look at an expanded list. I could have easilly found a discussion I participated in 8 months ago, but not anymore.
I find both of these changes to be annoying at times. There have been times when I wanted to review some things I posted in past discussions, for example, but I can't quickly find it.
I don't know if all these changes have been designed, or are a side-effect of something else.
The user deleted problem, however, seems to have been corrected. And the time-out that used to occur when having a message reply window open too long is no longer an issue.
