i've flip-flopped a couple times since starting, so i thought i'd ask the members what you all think.
both types of groups are public and, therefore, the content is visible to everyone. the difference is, in an open group anyone can join by clicking the "join" button, but in a closed group members must be approved by the group leader(s).
fyi - the group is currently open because i thought some might be discouraged from joining if they had to be approved. as for being approved, i have every intention of approving anyone who asks to join who fits the description of the group (i.e., participated at some point in the may 2011 ddc and/or anyone who had their baby in the month of may as well as late april or early june of 2011). our other group leader (Partaria) can let us know if she has the same intentions.
