As it turns out, I used the Member List on the old forum many times, and for the exact reason you cited. Many times a member has been MIA and, when trying to find out the last time they posted, ...well, that makes the task more difficult. Additionally, if the member has not been posting much in the past several months or so. Many times I have seen someone ask if so-and-so had been on lately, and when nobody can remember seeing the member post lately, I would go to the Member List and go through the myriad of pages (that IS a long list!!), and then would report back, as well as posting the link to that member's info -- just in case someone else wants to look up the info, last posts, etc. Many of those times I wouldn't know how to spell the Username in question, as I may not even know who that person is (though usually I did), but mostly I was having to use the list because special characters were being used, or in the case of very common names, there might be several pages of similar usernames. Just gonna take some gettin' used to is all. Heck, I'm amazed at how much progress ya'll have made already!!
Thanks for getting the puzzles up and running again! That has been a good resource for people to have, doing something fun, on-topic (usually), and a nearly endless supply.
