I'm writing this in IP.Board, but I guess this request concerns the tagging system for the entire software package:

I think others have mentioned this in various ways, but I would love to see better search functionality in the tagging system! It looks great, but apparently one can only search one tag at a time; it would be really great (for Forums as well as Download centers) to allow Boolean AND/OR/NOTs to the tag search system so one can search for multiple tags and exclude others.

Apart from that, keep up the great work! :D

I think I have posted this as a query earlier. We would also like the ability to search by more than one tag.
