Regarding the member you mentioned in your post, he was asked to explain a post which was perceived as a security risk but he never did which left us no choice.
I never understood why he was so evasive about answering the questions about how he could:
1. Take a "quick look at my network log for yesterday"
2. "Capture several thousand takeoffs and landings from the network"
3. Refer to his "network capture log"
All he would say is that "My usage of RB and the network does not involve any functionality other than that provided by the software to any user of the system." Yet nobody can understand how he managed to create a network capture log. All he needed to do was answer that simple question to refute Airnav's allegation of "hacking".
Back on topic. I would like to see the ability to view all the posts of a user reinstated. It often helps to be able to answer a query if you can view previous posts by that user.
Being able to look at a users profile is less important to me.
