A lot of the others have made some good points. To expand on some of them though, there is a lot of different ways to get recognized. In my opinion the best way to get recognized as a person that is involved and helpful is mainly by the quality and consist quality of your posts. If you continuously post some good feedback, spark good discussion, and make good points in threads people will start to recognize you as someone that is really serious about the community. I'd suggest not just trying to post everywhere to boost your post count as quick as possible, but try to make posts with depth and quality. I personally always try to make it a goal for myself to make my minimum post at least two lines long on my screen and still have good helpfulness and relevance to the topic. Obviously posting is not the main part in community recognition, but I feel like it is a main point.
A few other things that are good to do is keep good and mature trading habits. When you maintain mature and organized trading habits people view you as professional and a real player in the community as well.
Hanging out in the irc and getting to know as many new people in the community as possible doesn't hurt either. In the irc there is often discussion and people requesting help. Some people may argue it doesn't help but I am fairly confident that it does, you get to know more people and build relationships with them.
Try to get into a routine and stay active with it, there is a lot of useful tips that some users have provided here, but other than that I agree with what Firez said. Be yourself and do your normal thing, people will start to notice and recognize you if you are a good member in the community.
