I consider myself fairly Internet savvy, but I freely admit not seeing or noticing messages on the side of a webpage, since I am focusing on the main information in order to post a link either for information purposes or support for what I'm posting, the latter of which I think is not only acceptable but helpful.
And I have to say that as a poster who is usually in good standing here, I resent the subject line of this thread. It never occurred to me that anyone is secretly trying to sneak in a message of any sort.
But if it happens accidentally, then fine. If the mods see it, they'll take care of it. End of story.
