I didn't warn you, I'm not a mod or a staff member, (you might be getting me confused with
seraphimd2 who isn't a staff member either)
I'm just member who was confused by your strange post that had no bearing on anything in this thread.
When/If you get warned I'm pretty sure it won't be in a public thread, you'll get a message in your Inbox, and before that you'll get a notification that your posts have been deleted for whatever reason, in this case it will likely be "Rule #1 Offtopic post"
I doubt heavily that you will get banned without a very clear warning, and posting a few off-topic messages won't even get you a warning unless you really push it.
Personally I've had about 15-20 posts get deleted without getting in trouble, The secret is don't complain, if they delete your post accept it and move on with your life, the staff here aren't monsters looking to hurt you, they are just trying to keep the forums orderly.
if you think those others are doing something wrong then you can hit the report link at the bottom left of their post, and tell the staff here what you think they did wrong.
