So a parent from Runkle built this great site where parents can blog and share info.  That was  a big piece of work!   Now, if you are at a school or group that doesn't happen to have someone who can spend the time building such a thing....you can jump on YourBrookline.org and set up a group in about 10 minutes.  It can be a closed group, an open group, invite only, etc.   Take your conversation off the playground and bring it online!  Start a group on YourBrookline.org and chat all through the cold winter months.
