It is now working properly but (even after logging off-and-on multiple times) . . .
The TWW “Howdy, Jeff Hudelson” banner (which appeared on all other TWW fori) was not present and the message at the bottom of the Renaissance page said that I had to be logged in to post a new topic.
So, General Slade, I wasn’t trying to imbed links . . . I couldn’t do anything. But now it seems to be working properly . . . so “thank you” to whoever/whatever fixed it.
