Talk:OLPC Human Interface Guidelines/Activities/Activity Basics

A couple of questions that appear to fit on this page, but weren't addressed (or at least I didn't see it):

1. Can activities be locked to 'current members only'? (This would allow the activity restriction to work properly - lock it to current members first to prevent new entries, then narrow the scope further as people leave. Otherwise new members might join as other members leave, making it difficult to narrow the scope of access)

2. Can activities be 'forked'? (e.g. starting a new drawing of your own based on an existing drawing instead of resuming the original) What would trigger such forking? (e.g. would going back and resuming a 'kept' version of an activity be enough to create a new fork?)
