problem 1: the search feature.
This problem can cripple a site, type the letter 'a' into the search box and press enter (no quotes), the result will dispaly EVERYTHING
Fix: the search option needs to drop the categorys from the results (wasted resources as people only want the listings), the search function needs a check of the length of the query, should be a minimum of 3 characters. it needs a max result limit (say max of 200 results displayed) as to stop resources being sucked up.
also has other bugs like time zone search option is all out of wack.
