Edit: This post no longer makes any sense because Trying changed his posting name back to Trying instead of Rangerwill.
Basic summary:
Rangerwill posted a goodbye thread, deleted his account, and started posting under the name Rangerwillx. In this thread someone mentions that he shouldnt have deleted his account because the name is now available. The next post is from Trying posting as Rangerwill and it says, "Too late". At this point all of the posts which have ever been made by Trying now are listed as Rangerwill.
In the end it doesnt matter. If you delete your account you have no rights to a username on the account, but it was fun to try to determine the identity of the "new" Rangerwill.

Was considering a necro but got distracted when I saw post 47 of the old ask a vet thread. All of Rangerwill's posts have been changed to Rangerwillx, so whoever posted this was not rangerwill at the time.

This was the gem I was looking for. You will notice "Rangerwill" posts several times in this thread. Also you will see that post 38 refers to a player who has not posted in this thread.

And again
is the old Rangerwill. Since he's now quit and deleted his account, it seems a forumite has taken his old name and is now currently using it.
Edit: Oh snap! I didn't even make the connection when reading through your links Sir-Didymus! I see what you're Trying to do there!
