Portuguese lessons

I am an English expat living here in Lisbon. I've been here for about 8 months now and my Portuguese is crap.

Does anyone know a good place to learn Portuguese?

Hello Chris,
I am a retired teacher and I suppose I would be the right person to teach you Portuguese. Unfortunately, I live in Oporto, not Lisbon. However, I think I can be of some use to you, because I expect your difficulty is catching the rules of the language. If you agree, we could have lessons by email: I could explain and set exercises and you would return them and ask questions.
If you are interested in trying, please write back.
