I have noticed many users only post one message, and are never seen again. I do not know if it is because once their question is answered they never come back (without even saying "thank you" I might add) or if they just forget about the site.
I would like the mods and The Geek's opinion on creating a Guest posting option for those that will only be using the forum one time.
It could use captcha to keep away bots and be restricted to "X" posts from any given IP (which is not full-proof, but it may help some). The guest posts could be separated into a separate section (Instead of Win XP, Win Vista, Mac OSX, etc.) and the drop down that has these would simply be there to determine the area of the question. This "guest" forum could then be purged after "X" amount of days or moved into a permanent forum if information that may be useful to many people were to arise in it. (This of course would be controlled by the mods.) I suggest this because often the 1-post users ask very basic questions that may already be on HTG. Doing this would keep the size of the database down, though I would assume not enough to affect much, but it may help keep it more organized.
As a plus:
I was thinking of this to keep names from being taken up. For example if a user has the name "user123" and only uses the site one time, and an individual comes along who would really like to use that name and will be a regular user, then "user123" would still be available.
