you and me both! because the site is free I think they deliberately make it a pretty erm unfunctional ... if such a word exists. What you have to do is hit the 'forum' tab and then either reply to a discussion or start a new one. There is a link at the bottom of the text box that asks if you want to upload files.
I'm planning to maybe reorganise the content using the JAA topic list instead of the rather random 'throw it up' way its developed.
As for the lack of response, I reckon people are just shy .....
Thanks for your input
