You are able to recieve them. There is a button there so that people can send them to you. Is this what you meant?
As for sending them to other people...there should be a place right under the Sanex Hero banner at the top of the page, on the right side of the banner underneathe that, that says "Private Messages" with an underline. Click that and there is a link in there that you click to compose them...it's self explanatory once you get click the Private Messages thingy
