SmallGroups.com is a site which provides excellent resources for small group leaders and coaches. There are e-mail articles which are sent frequently to those who have signed up for them which give a variety of information and tools for those involved in small group ministry or even those who desire to stay current with small group movements.
They have recently launched a digizine which you are able to sign up to receive. If their previous offerings are any indication of what the current offering will be, then it will be well worth your time to go to the site and sign up. They are also doing a drawing for a free IPad. Not too shabby.
