A facility where it would be possible to search 2 posters names to see what threads they've both posted on and therefore communicated on before?
An example:
I'm on a thread and Valpollicella comes on and it leads me to think "Hmmm, I've spoke to her before - what was that about?". It would then be possible to search and see where you've connected before, and your memory would be prompted - "Oh, yeah she's the one that really like Bombay Mix(or whatever) - I remember now!"
I don't think I'm explaining this very well, but there's loads of times someone name sets of a little "ping" in my head and I'd like to revisit previous conversations.
Does anybody feel the same as me, or is it a little bit stalker-y?
