I'm a novice with web design, but I just put together a website for my son's high school lacrosse team. We'd like to link to a message board forum that I can moderate. I've looked around, and there appear to be a few sites that will provide a message board service for free but include advertising, which seems to be OK with the coach and parents.
My questions are: Is there anything special I should look for when selecting such a site? Do you have any personal recommendations?
