I've been looking for a post today, and using search more then I ever have, I would like to add a few suggestions.

1. On search dates, add 15 month, 18, month, 2 years, etc. Also add "since join date" which would be the day(month) that user joined.

2. Abilty to select specific but multiple forums at same time. Like body/interiour and apperence/detailing at the same time/same search.

3. Attach pics only threads, or non-attach pic only threads, or both. This could get tricky because of hyper link, but might still help.
