I have made a listing of them on UBBWiki: Admin Log Names; most are painfully obvious since the admin scripts and the log names are almost identical, and most others one can guess based on the action (such as Watched List supporting watching Forums/Topics/Users) and the ability to LoginAs other users from within the Control Panel).

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
