I'm also in favour of a MorphOS club. I'm a member of the MandrakeClub wich give's members free download of the Mandrake Linux retail versions a month before it hit's the shops. And there are several other benefits.

It's a good idea to start a MOS club wich allows members to download beta versions, free download of the retail versions and acces to bugfixes etc. Mayby it's also possible to include an automatic update service in MOS 1.5 for club members.
There should also be a freeware MorphOS version available to people who are not a member of the MOS Club so they can try it before bying.
