Notification rules - request updated, but group not notified

We are currently running v6 with the latest hotfix/patch - awaiting full release of upgrade pack to v7.0 before we make the jump.

Anyway - something a few technicians have mentioned is that when a requester updates a ticket via email, and the envelope icon changes to red on the summary screen, the technician working on the ticket (if assigned) doesn't get an email letting them know the requester has updated the request? in the instance that the ticket is not yet assigned - surely the group the ticket is currently residing in, should get an email sent to them informing them of the tickets update?

anyone please confirm - from looking around the forum it seems hundreds of questions go un-answered by tech support....Sending them an email to reply to is more hassle than it is worth with my experience so far :(

thanks
