I assume You're familiar with Coursera. They have several on going classes that are relevant to LW such as:

1. Intro to Logic.

2. Probabilistic Graphical Models

3. Introduction to Mathematical thinking

Would anybody be interested in taking these classes with me?

I think this is more suited to an open thread.

Yes.

Intro to Logic, perhaps! It depends on what your schedule is like and what you mean by "taking it with (you)"
