My understanding is that if we use unlocked rooms there is no charge. When the debate arose regarding locked/unlocked I made it clear that I would join either but actually preferred the open rooms as it meant the possibility of non Mudcatters finding out about us and if they wished visiting the site and maybe joining. I know there have been one or two problems with nuisance visitors but if the admin is willing to deal effectively with these idiots then the room can carry on . If its a choice between paying for a locked room or getting an open one for free I can't see an arguement for paying!
Unfortunately I doubt whether our protesting would have any great effect on paltalk although that doesn't mean we can't try.
