Feature Requests: Messaging / Mailbox

Hi There, This has probably been asked already but I think it would be a great idea to have a mailbox or messaging service for each member. I often find myself in a dialogue with particular members of the site, especially when I am seeking advice and it gets a bit long winded. I am very conscious that everyone else reading that forum has to put up with repeated questioning and longwinded explanations in this dialogue. I am sure it would be much better to do this off line. I would be very reluctant to post my email address in a forum (any one can access it, spamming) whether I be advertising for training partners or seeking advice off-forum. A mailbox would provide the privacy and the means necessary to open dialogue between members of the community without filling the forums full of personal conversations. Just a thought Lex
