While advertising one's self on a message board that few college coaches read is one way of getting the word out, the NUMBER ONE way of accomplishing your goal is to pick out the colleges you are interested in (being practical-DI and/or DII) and writing the coach an e-mail expressing interest and attaching a comprehensive bio to the e-mail.
If you wait to be recruited, in most cases it won't happen. Stay on the coaches as time passes, giving them updates on your performance. Also, be sure to attach a copy of your league and high school schedules. You will hear something early next fall when they are out beating the bushes for recruits.
Also, the higher your grades and SAT scores, the more looks you will get. They want to meet the academic expectations for their conference AND win games.
Good luck.
