Ok, one instance I ran into problems was trying to find pictures of silverxj's Cherokee. If you don't know specific words to find what you're looking for, it's a pain in the ass.
Look at thread #1. Because those words are in there, it's #1. There needs to be general things tagged with posts, like pictures and what not.
I'm not trying to be a crybaby. With enough searching I was able to find what I wanted, but since PP brought up his problems, I thought I'd just add the trouble I've run into sometimes.
When I'm searching, I don't always know who posted, what the thread title was, what page it was on, and the exact keywords they said. If you don't know at least half of that, searching can be a pain in the ass.
