Such as the ones on activebass.com? That is the only thing that still makes me go to activebass, the composing program, the tuner, and the metronome. I think something like that would add greatly to the site and increase the amount of people visiting.
Personally, i see that as activebass's thing. I don't see a need for two, and those things can always be downloaded as freeware from somewhere...
Agreed, Talkbass is pretty unique right now. A bass specific message board. There is no point to directly ripping off another site.
