Well now, this is interesting.
When I came to TS via my usual bookmark I got the same "Guest" situation. However I immediately went to the Tech Forum anyway to read what you all had posted. I figured I'd try your suggestions first before logging in to reply.
After looking over all your kind and comprehensive ideas
, I looked up at the top of the page to see "Hello krissel"!
What the...?
Now it sees me but I didn't log in.
Soooo, after a bit of exploring, I discovered that somehow the problem was related to both bookmarks to TS that I had been using ever since we moved here. Why that should be, I have no idea.
I've created a new one which seems to recognize me upon arrival.
Thank you for all your advice.
