I have not changed anything in my profile (other than dropping Hilton Gold & UA1K under my handle) since I created it years ago & previously I could see threads going to way back when.

I frequently go back several years when we're considering TB matters and I'm looking for something, and the threads have all been there. I've done so a few times in the last few months when we were considering motions & they were all there. It was them not being there today that brought it to my attention when I was looking for something that was from 2-3 years ago.

IIRC this change in view happened previously & I think I might have posted about it thinking it was a glitch, but of course I wouldn't be able to find it if it was more than a year ago

Anyway, I've gone into my profile to make the change to forever, so hopefully it will stick. For anyone else who's interested in doing so, it's under the Edit Options section of the stuff listed under your profile & 3/4s of the way down in that section.

Cheers.
