It looks as if 2500fps was combined with Sarge. Basically, Sarge's posts were moved to 2500fps, and 2500fps was renamed to Sarge. However it was done, this was the net result. Sarge therefore has a join date of 8-28-15, making tech the latest member.
I suspect that the post author ID was changed to 31151 in the SQL table for each of Sarge's posts, then the username for 2500fps was changed to Sarge in the SQL table, and the original Sarge was deleted.
I had looked for 2500fps, a few days ago, and only came up with references to that user, but no posts authored by that user, and no user by that name in the members list. I was positive I'd seen posts by 2500fps, previously. When I looked a bit ago, all the previous posts have returned, and Sarge's join date changed.
