Is there a search bar for the forum or something, or would you have to dig through the pages?

There was briefly, but it caused too much of a performance hit. Omn is, last I heard, trying to figure out how to get it to work.

In the meantime, try doing a google search using "site:http://dynasty-scans.com/forum" followed by your topic.

Or type the same string but into duckduckgo or yahoo if you're averse to feeding the devil that is google.
