I’ve been working around that with some ‘net-wide “eventide forums {specific keywords} {user name}” searches, if you remember any of that.  Not the greatest method, but sometimes you get lucky.

I often have to look up my own stuff to refresh my memory.

When the forum got updated a couple years back, it broke all of the existing links.  No more “…/community/…” subfolder structure.

You can manually insert “… forums/topic/…” if you happen to stumble across those old links inside a result in a ‘net search.
