Hiding threads / Customizing VB to interact with Moodle...?

[embryofilms]

Hi.

I'm not sure where to put this, but since I'm using VB 3.8.4, this seemed
like the best spot.

I have a VB forum that's part of an educational system, which is done
through Moodle. What I need to do is have certain VB forums and threads
remain INVISIBLE to people who have not reached a certain point in the
Moodle course content. For example, imagine there are 20-lesson in 2
Moodle course modules. If someone is on Module 1, Lesson 4... I can't
have them see the VB thread for Module 1, Lesson 5. I don't even want
them to see the VB subforum for Module 2.

So, two questions:

1) Is this kind of functionality available within VB or its plugins? If so,
can you direct me to an appropriate link?

2) If it's not part of this functionality, I'm assuming it would require some
custom programming. Where can I find a programmer who could help
me customize something like this?

Also...

When I run a second group/course, I want them to access the original
threads -- and all the replies that are on that thread -- AS the Moodle
lesson is revealed. Same questions as above: If the above VB functionality
exists, does this, too? And if not, any idea where I can find someone to
help me customize?

Thanks in advance!
