new ports and maintainer

[petr at macports.org]

Hi all,
I am wondering if there is a well defined policy regarding maintainer ship for new ports. 

I understand that it is quite usual to assume maintainer ship when contributing a new port and that nomantainer is more usual for abandoned ports. But is it usual to commit new ports as with `nomaintainer` as well, or should this be avoided? What to do with ports where the contributor does not assume maintainership? 

Any thoughts? Thanks!
