we always seem to get the same questions/topics/subjects brought up.

i have seen on other forums a rather useful tool.
when the person starts to type in a title for their post, automatically they see titles of previous posts of the same topic.
many times, the topics of new posts have be covered before, but the person can't find them, so they post it again for the millionth time.

so if i start to type "Which insurance company is cheapest?" they will automatically be shown posts of similar topics. They can then see others have posted and not submit the new post.

seems to work well. seems like a really good idea for this site.
