[generic issue, not vcproj2cmake-specific]
it's a bit disturbing to have Project Admin -> Support Page:
reset the pre-defined URL: content (mailto:firstname.lastname@example.org)
to empty once choosing e.g. Wiki and then reverting to URL (I had to completely leave this admin page and re-register all my couple content changes in order to get to know the prior URL). The prior URL content ought to be preserved for restoration, if possible.
Thanks a ton for a likely nice new interface and a rather smooth migration!
