Custom Wizard definitely has a broad range of use/capabilities.

However to limit who can edit a wiki. Use Groups and category permissions.

So for example Bob seems to be very knowledgeable and has asked if he can help/submit & assist maintaining the database(s).

He applies to join Tree Wiki Group.

Tree Wiki Category security settings

- **Everyone** - See
- **Tree Wiki Group** - See/Create/Reply

You can also set a Setting that when someone tries to post in a wiki group topic it displays

“You must be a part of x group. Would you like to apply?”

This can be configured to be a link to take the person to pm group owners.

From here I will leave this for someone with better knowledge to answer your other queries.
