accent

Ok I've seen a topic like this one on here before, the only thing is I don't see anywhere on here to leave an attachment. I am an actress and I would like to have help perfecting different accents, such as a British accent. Since there isn't an attachment option on this forum could I have some tips, please? Now the British one is just the first one that has come to my head I would like tips on other accent.

Thank you, Mindy
