Choicy, when and if you decide to post there are several approaches which you may wish to consider depending on what desired level of acceptence you are looking for.
1: You could speak soley about sports, have statistical data and perhaps even a proven method and post plays. While on the surface, this being a sports forum and all that may appear to be your best option, it will severely limit your amount of interaction with the board as a whole.
2: You could opt to speak freely about your hair, how you measure up to a standard toilet paper roll and basic information about your balls. These are options if you are a male that will provide you with an enormous amount of interaction.
There are plenty other options for posting styles from negative Andy's to narcissistic scientist to angry penis', choose you posting persona carefully as it is very difficult to remake oneself after that initial post.
