I would start by reaching out to Sonny (sdaniel) and Wendy (Tangled22) to see if they are still interested. I suggested it a few posts back but I have not heard anything. Then start a list in a post which you can go back and edit as the group grows. I can also add your Group 2 names to post 1 of this thread, where it is easily accessible. I waited until I had the list before I compiled full information, but if I were you I would start by getting it up front. You'll want to do that in PM (private messaging) so it's not blasted on the board for anyone not in the group to see. Compile the information as follows:
DIS Name
Family Name
Adults' Names
Children's Names & Ages
Stateroom #
Food Allergies?
E-mail Address
* If the group is big enough, you could choose to assign days to deliver gifts, in which case you would ask if each family has a preference.
Enter the information into a spreadsheet, e-mail it out to the group, and you've got yourself an FE Exchange!
Wendy and Sonny are both also on our FB page (the link to which is in post 1 of the thread), if you want to try starting over there. Let me know how else I can help! I am happy to send you a copy of the Group 1 spreadsheet if you want to use it as an example. Just PM me your e-mail address.
