Addendum: I can now report that the bally thing works, too!
At least PayPal sends a note telling me that someone donated. I still haven't figured out how Kathy does little image thingie. It must be a mod, and I haven't yet had time to go hunting among the mods. I'm procrastinating on that until I can upgrade to the latest version of vBulletin but before I do that, I need to reconfigure the database for the other site, and meanwhile my big machine is busy loading Body Shop, and I'm sure that the power failure last week and the air conditioning failure on Friday come into play here somewhere.
