Just a few ideas from being active member of other forums -
'Overseas' - where ppl abroad can interact about what they have found etc?
'What to buy and where from' - this could just be where people search for offers eg of a supermarket has an offer on?
'Through the stones' - basically different threads where people of similar weight share losses and experience. I think this is nice a someone with less to loose will loose slower but sometimes might get hung up on what others are loosing! It has happened to me!
'off topic' - general convos about books, tv progs - owt really!
'vegetarian options'
'Weekly weigh ins' - people sharing their weights on their chosen WI days
'Q & A' - place to find answers and ask new questions!
'DD low calorie alterntives' - could be a place for people to give new ideas so treads could have names like 'mash potato alternative'
Hmmmm.... Would make this forum quite like others - not sure if that's what everyone is after?!
