Looks like not a lot of responses from the Collanos team lately ... gives me some uneasy feelings. Then again it may just be me. Here are some of my bones with reference to security

:
1. Guests - should not be able to invite others
- should not be able to uninvite others
2. Participants - should be able to invite others but the invitees will only get guest privileges
- should be able to uninvite guests
3. Managers - Only group which can change permissions of Participants and Guests.
- can invite and uninvite everyone
- the default permission when inviting someone should be "Participant"
When Managers uninvite others, the workplace of the uninvited person should be totally deleted from the uninvited's hard disk.
Other issues:
1. I thought that 1.2.01 will introduce offline notification (email) ?
