I would think that it is sufficient to only allow non-anonymous email accounts. For example:
* an institutional address: .edu, .ac.uk, ... * a sourceforge-address associated to an active project * an address that has been used to post to google groups before (use search) People that want to use their gmail account, say, can still change their email address on the trac preferences. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
