The usecase is a big non-profit-proces with many non-techi-persons in different groups. Most of them are not techi enough to handle more then their private-mailaddress (some of them have enough difficulties with those private mailadresses at first =) ). and for sure, we don’t want to share their private-mailaddresses on the website in an open way. Using a webform is a choice about “low threshold” for all envolved persons - incl. Admins =) We have own group-mailadresses for some of the main-groups. but there are several groups starting and stopping-work… so there is high fluctuation and also these groups don’t have always a unique name… after all: it’s unpracticaly to implement forwarding-mailadresses for them and it would be much meta-work for us admins.
so… yes, it is also for protecting mailadresses but also for avoiding to much work for us admins =)
