I'm creating a landing page inside of a site definition.
This landing page will have all blank web part zones.
What I would like to do, is have the zones initially set by someone like a Site Collection Admin, so there are a group of core web parts.
Then the rest of the users can customize the remaining slots themselves.
I'm looking for two options: One, can the core webparts be locked down, so they always display? Two, at the very least, can I make a page personalizable while restricting editing?
