Features / Usability

Hi all,

I'd like to implement the following setup but I am not sure how. I have looked at the docs but couldn't find something that would explain this scenario:

I want to use our tiki installation for our group's documentation of e.g. projects (mainly wiki, sometimes blogs). I'd also like to use the calendar for meetings, telcos whatever. All this must be restricted to our group, e.g. grp_owner. No one else must see the content.
But certain pages (wiki) or blogs I'd like to share with "external" partners, e.g. registered users in grp_external. These users from grp_external should only see the pages they are allowed to, but no other pages from tiki.

Is that something that I can achieve with tiki?
Can you point me to the relevant docs? Any tips & tricks?

Hopefully I don't sound too confused 😉

thanks,
Sven
