Hello, I am currently creating an ongoing series of Topology video lectures and looking for students of an appropriate level for some accurate feedback. They are much in the style of the popular Khan Academy.

Thank you for your time.

Hi Sekky;

The vids are nice. Thanks for providing them.

**In mathematics, you don't understand things. You just get used to them.**
