It happens. We all run into it from time to time. Best thing is to not treat it as a personal attack on you, just a reminder of what can post where.
I much prefer the forums here where they give you a heads up on what you did wrong, rather than on some forums where they just delete your post and you think there was a glitch, so you re-post, then they terminate your account because you violated the terms twice! Shady business practice in my opinion
Thankfully the mods are all nice here, and if they don't post it in the forum, they drop an email - so it's all good.
