I have joined some groups in LWV. But just to put my 2 cents in, I don't think these groups will ge the participation the old system did. For one, nothing comes directly to my email system. So I have to :
1) go to the LWV website
2) click on log in
3) log in
4) go to groups
5) pick which group I want to look at
6) for each post in each group, you have to click on the post in order to see it in full - they only show the first line of each post.
This is too much trouble to see something that used to pop up in my email.
