Forum rules
The rules should go without saying, but here they are:
Use your real name, and if you use an avatar, make it a picture of you. This is for real people only.
Don't cuss -- I don't mind, but others may.
Don't get personal and call names.
Stay on-topic -- start a new thread for a new topic. Try to get it in the right category. If you have a question about what that might be, ask me.
Be informative and provide useful information. Please search to see if your question is already answered before asking again.
Keep speculations and general gassing to the forums/threads meant for them.
Don't ask a question, then start a fight over the answer. Google/Wiki things first if you can manage.
Don't anger me -- if you do, you're toast here.
Don't put copyrighted material up here and get me in trouble.
