This has been a common problem in many FAQ sub-forums. Some have a notice, i.e. a "stickie," instructing others to NOT post to the FAQ sub-forums. Also, most MOD's, who do post to FAQ sub-forums, will Lock their posts.
Ideally, a MOD should move general Discussions FROM FAQ sub-forums, out to the main forums.
Just my thoughts,
Yes, I agree and the MOD in this case has moved the posts to the LC Designer forum. I was just surprised that the ability was there at all, as it just seems undesirable.
I do not even pretend to know all the possibilities, when one either creates a FAQ Sub-forum, or administers it, but would think that there IS a way, to actually restrict postings, such as Open ONLY to MOD's, Administrators, etc.. Maybe someone with knowledge can instruct us both.
To date, the message to "Please Do Not Post to this Forum," seems to be the norm, but many posters do not read that, or heed that. Same for a few of the Root Forums, where someone finds a way to post there. Happens every few months, from my observations. Still, some sort of Lock should be possible, but maybe not worth it?
Yes it's possible to limit the posting permissions on a sub-forum, though whether it's used depends on who set up that area of the site, and how the mods responsible for that area wish to operate. There are situations where you may want to reply to an FAQ (to ask for clarification, etc) so a blanket lock on everything isn't necessarily the way to go. It depends how often the mods scan these 'backwaters' for wayward content and move it into the correct place.
