First question is this: In build 8206, if I continue to manage the technicians in the default settings groups from the "Support Groups" screens, are those changes propagated through all the site groups that were originally created?  

Second Question:  We also have some old MSP groups (previously called Technician Groups) that we created in previous builds.  When I attempt to edit those old groups and change technicians in those old groups, those changes DO NOT appear to propagate to the same-named groups in all the sites -- is that correct?   

Third Question:  Given behavior in second question above is true, then how can I delete an entire set of Support Groups from all sites and accounts AFTER some of those groups have been used in Service Requests?   OR how can I re-propagate that old, previously created Technician Group through all sites in all accounts after I have made some edits to it?
