Ohhhh i can't join in! :P
I think it's a fantastic idea - good luck to all participating.
Maybe if it's something that goes well, it could just be something to organise to start each month, so to speak...? So groups who can start on Jan 1st can, and then Feb 1st, March 1st, etc.
I don't know if the mods/admin would agree to it, but it could be similar to the layout of the belly buddies threads - "Body Challenge Buddies - 01/01/08" etc. Might encourage more people to give it a go if it's a consistent or regular thing...?
If bubby comes early /on time i'd be up for starting march, but any later and i'd have to wait until april (provided no c/s of course).
I think it's a fantastic idea to have all our Belly Belly Buddies rallying behind us with support! And for me, i probably won't be a gym person so i'll really need the encouragement from other sources!
Anyhow, just an idea...
