Why two forums guys? Google and Avsim.Why not just one?

i need a mechanism, where i can send an email to every registered user of radar contact.not just the ones that read avsim, or the ones that read flightsim, or the ones that read simflight, etc, etc, etc.the google group allows me to do that.the google group is not a support forum, google group members can't send emails to the group. i can only send emails to them.if people want to wait for an announcement on those forums, that's cool.
