If you are talking about a group on the internet through the website:
Go to Groups at the top of the page and hit it. The screen should show the many groups. In the upper right hand corner is "ADD+". Hit that button and the screen should show where to input your group information.
If you are talking about a face-to-face group near where you live, contact Bonnie Bright.
If this doesn't work, get back to me.
