It seems I can't quite do what was once trivial: locate all threads in which a given user has participated.

I think I can use the search function to locate all threads a user has posted to with certain keywords.

I know I can view all of a user's individual posts via that user's profile (though the link says something like "recent posts", which made me ignore it for a while).

But if I don't care about the content of the thread, just the user, I'm stumped. Any help?

Thanks.
