How do I thank someone for something specific, like "Thanks for participating" or "Thanks for coming"?  I know it takes за, but I can never remember what it looks like after the preposition.

Thanks!

Hello,

I work full-time, but would like to take classes on the side. Could I use the verb "подучиться" to describe this? If not, what word is best?

Thank you!
