Ya I don't know if that will be effective or not, seems that the immediacy of texting might be just as useful, it would be interesting to see how a bullying twitter account goes, no doubt you can find some to monitor.
I suspect at best email might turn out to be a secondary aspect of some support, outreach web site. typically the need to submit an email to register on a site, you could offer an optional weekly newsletter, inspirational email to get the ball rolling.

There are a couple of free forum hosts out there like createaforum.com , getting people to find it may be the biggest challenge.
