Salt water, out of state reports, and a forum dedicated for guys looking for a partner/ride/etc.
Sure, salt posts goto warmwater, but should they? Much of our sw discussins are Jersey shore, and that's technically cold sw fshing.
Reports... Yes, this is PA fly fishing, but of course there's a home for other states (and salt). It would be easier to find the less numerous out of state reports, as well as preserve the stream reports forum as a long term repository of PA-centric knowledge.
Finally, a forum to find fishing partners. Yes, people currently use the Stream Lcations forum, but it's not really appropriate. It's a great forum idea, it encourages new signups and partcipation, but most of all it encourages a sense of community for the site as a whole.
