1. Will Clubs show the Page that contains the database category, or only the Database itself.
The Page that contains the database often contains elements like filters or custom widgets. Whereas the Database is, well, just the database template.
2. Show Club Content Areas - This setting is all or nothing to all content areas in all clubs. This is an overly broad setting.
I can see how admins may want to show club Pages database in the Pages database, but perhaps not at all club nodes (or vice versa).
3. News - This is more of an observation, but it's clear that the overwhelming common usage - albeit not the only one - is simply the need for News. IPS may want to think about shipping a simple News function for clubs. I have several clubs where the owners have used Blogs for several years now as a news system.
4. Search - Will members who don't have permission see search results, profile activity, and / or activity stream from club database fields?
5. Choice of Databases - Will admins be able to choose which databases can be displayed in clubs, or is it all or nothing?
I like the concept of integrating Database categories into Pages and its giving me some food for thought of building some foundational databases that any of my 40+ clubs can use.
