Forums is a great way of getting information and discussing every bit and pice when it comes to flyfishing/tying.
Active forum with a good fly tying bench section and SBS
A part of the flytyingforum.com, but with focus on classic wet flies, streamers and salom flies (classic and artistic)
Not a very large site, but have some tying forums
Fishing, patterns and other topics related to salmon fishing
Need a account to view content though, but have a fair bit of good content
Some subforums not the most visisted, but some nice patterns and discussions
Localized forums are a great place when you need to get in touch with someone in a country you are travelling to, google translate will normally help out with translating the content so you can know where to post.
