Can i just say well done for stopping photo ads from being trawled by the search engines.
However could you add the line into the file
Disallow: /swingers-forum/
For those that dont know what this means, it means that every Dick and Harry cant search on the internet for your username etc etc and get access to everything that you've typed on the forums ....... i typed in my username and google pulled up messages that I typed back in 2005..
I know that having a forum that is trawlable will generate a lot more traffic to the site... but think about the privacy of the people on here!
