Hi,
Lot of volunteers are using email to communicate when they discuss wikimedia related issues. Even if it's not a big problem to use personal email there, lot of people, especially administrators do not want to uncover their personal email. Lot of them even have a special private mail for wikipedia purposes. Although wikimedia has own email server on wikimedia domain, it's being given to paid staff only, so question is if it would be worth of having an email service for volunteers who request it (it should be probably limited to users who match some criteria) or just a forward service which can help us to get our personal email hidden (this would not eat space and would be very cheap). I understand that people from foundation might have concerns that volunteers with wikimedia.org emails could cause some troubles or people might be in thought they are employees, so why not to use some another domain, like wmflabs.org for developers and wikipedia.org for wikipedians for example (other domains for respective projects). What do you think?
