Planning to implement forum search capability soon... [EDIT: someday ]
Update: I'm sorry that this feature still hasn't been implemented yet .
As a temporary solution, you can use google.com to search the Pixel Scrapper forums if necessary.
Just type this query into Google:
site:pixelscrapper.com forums [whatever you want to search for here]
So for example, if you wanted to find posts about cats and dogs you would type:
site:pixelscrapper.com forums cats and dogs
