I'm not a group type of person. I enjoy visiting with folks, but I also suffer greatly from meetingitis ;). We already do seminary, YW, activity day, piano lessons, dr.'s appointments, etc. The last thing I want is another meeting to attend.
We had a group of preschool mamas in our ward who were all planning to homeschool. It dwindled as the time came to choose between homeschool or public school (not a criticism, just a fact). There are still several of us in the ward, but we are all busy and aren't on the same page when it comes to curriculum.
Like Julie, I have found most of the LDS groups to be associated with TJED. Not knocking it (my sister's TJED kids have turned out great) but it just doesn't fit me. So, we do our own thing.....at home. :)
