Most forums collect browser version information (and OS info) from each comp that access the forums. From there you can get all the stats you need.
Yep...but I asked...
Can you tell even if the browser is set to report something other than the actual OS / Processor combination that is installed?
For example if i'm using my Linux machine and have set Konquer to declare itself as a Mac running say safari when it issues a get request how would you ever know? - oops given it away now.

(It's actually reporting what it really is to PPRune as PPRune works well with standartds based browsers.)
