I took your advice (sort of). Rather than create a new account, and since I wanted my account "Basil" to be the only admin account, I found every field in every table that looked like it contained the user ID and I ran UPDATE queries to change "4" to "2". That seemed to do the trick. I am now user #2 and new members are now receiving the PMs like they should.

NOTE: I am going to be clearing all my tables and re-importing my classic data once I have threads set up the way I want (so I'll have the latest data from classic). I am going to write a small PhP script (with HTML interface to enter server and DB info, old uer name, new user name, etc.), to do the queries in one operation and make the change from "old user" (in my case 4) to new user ID 2. If this is a common problem, do you think the folks at UBB would be interested in my little script to make available to others who are converting from Classic who might have this problem?
