There are many different ways for you to jump online with your sports enthusiasm. The most popular sports websites right now are actually just blog sites. You could install the WordPress script to your website hosting account and find a fancy sports theme, or perhaps even find a theme relating to your favorite team, and then start blogging about whatever you feel strongly about. You could do weekly write-ups of the previous week's game, the upcoming games, and everything in between.
Connecting your sports website to your social networking websites is also very popular. Using Twitter or Facebook to post small, frequent comments about your team and sport interests is a fun way to participate in active dialogues about your favorite team.
