I agree with everyone here...
I also wanted to know how long you have been using forums signature blocks?
Because along with any other traffic generator its not going to happen overnight, it takes time. Some longer than others but still it takes time to create a good presence on the internet.
Also when posting in forums don't just do it because you're trying to get traffic because its obvious in all of your posts. Posting without having a point to post or really having an opinion about the topic at hand is a dead giveaway... you know when you see some people post "I agree" all the time and nothing else. They always have something in that signature box so its pretty obvious they are doing it for traffic because they never say anything with any value to it!
Another thing make sure you are tracking every different type of method you use, that way you can see what is working for you and what isn't. What works for me might not work for you, but at least by tracking it you will see what isn't working and you can stop wasting time on that method.
Good luck!
