The ability to browse profiles via a members list (which used to be available) has either NO link or an inactive one? The only thing currently available is current ONLINE users or a members activity list which doesn't do much.
We have not had a members list for about two years already. The reason being is that it is simply too resource-intensive to pull a list of all 850,000 members from a database table that is very heavily used.
There is a list of the top 100 members that is probably more useful than the full list because the top 100 members will include most, if not all, the active members who post here. See the "Top Members By Rank" link the very top of the page.
