My rules of the internet:
Don't talk about real life people unless I'm okay with someone approaching them and saying "Hey! Do you know Mandark from the jaff forums?" or something like that. Same type of thing applies to locations.
Don't link from one forum to another unless the worst conceivable cross-pollination between them wouldn't bother you.
Generally, assume any information you divulge, in links, vital statistics, pictures, or audio will be abused. Don't give out info on the assumption it won't.
