O.k, kind of stealing this from Facebook but I think it would kind of cool if the forum gave you the ability to 'tag' other members in your post to maybe draw their attention to a thread you find interesting.
Examples could be in the Q&A section you see someone ask a question and know someone who would be the perfect person to give advice. You'd reply in the thread with,
'I'm not too sure about that, but maybe xxx would know?'
or,
'I think the answer to this question is blah blah blah, but I'm not 100% sure. Maybe xxx could confirm?'.
Those are just some examples. The use of such a function wouldn't be limited to just the Q&A section.
