Play Nice, Be Helpful, and have Respect!
This means keep the language clean, keep your posts polite, and don’t get into arguments over dumb things. If somebody responds to a thread you posted in poor fashion, ignore it, and the moderation team will quickly clean it up (you can always message or email a moderator at any time if you observe anything that is in poor taste/against the rules). Think back to what your parents and teachers used to lecture - if you don't have something nice to say, don't say anything at all.
Always remember that we are all unique and at different levels here - some of us are experienced gamers and forum junkies, while others are just starting out. If you’re on the experienced side, have patience for those just joining in on the fun and be helpful. With a little patience and a little help they won’t be newbies for long. Also remember that it is our differences that keeps this place interesting. If everyone was from the same place and at the same experience level it would be boring. Respect your other fellow players. We are all here to have fun!
