Because this site has no age restrictions or warnings, we really have to enforce all of the rules in all of the forums. If members want to make a "good members beware" room in chat, then they are welcome to do so. Chat requires membership, so our younger guests will not be able to see the entries. But, please keep in mind that Virtual Countries does enforce its Acceptable Use Policy when using any of our services. If the room gets too rowdy, then a moderator may have to step in and take action.
As for a Jokes forum, that's not a bad idea. Please post a message in the Open Forum to see how your fellow members feel. If the response is great then we may be able to add this as a permanent forum. But if there are few replies, then you are still welcome to start joke threads in the Open Forum. Please post a follow up here.
Thank you for your suggestions!
