Yes, I agree it would be nice. Perhaps there is some sort of "tagging" system that could be activated in VBulletin, the underlying BB software package. The idea would be to set up tags like:

Related to current version
Related to version 6.2 and later
Related to version 5.x

Another possibility would be a custom search function that excluded posts prior to the introduction of, say, version 6.2 (selectable, I think.)

Anyway, thanks for contributing! And the offer to help out is noted.

Cheers!
