The Saltwater Fly Fishing Portal is a community to target the niche of fly fishing in saltwaters. The site has been live for nearly 3 months but has just finally got the bugs worked out.

It has been optimized for SEO and holds very good rankings in both MSN and Yahoo (still in that sandbox over at google).
The site includes forums, fishing reports (using the blog system), articles (including fly patterns), and much more.

As you can see by going to the site it has also had ads implemented into the site placed at locations where they convert without annoying vistors.
The site has over 11,000 pages indexed in google and has received a PR 4 during its first update. Feel free to check out the site and leave your feedback about it.
