New Ethical Community focused Bitcoin Trading Site

Hi guys,
I am in the process of launching a new Bitcoin Trading Site and would like to get the communities feedback as to what they would hope for in an ideal trading platform.
I'm hoping this can be run on a not for profit basis- its goal purely to support the idea that is Bitcoin and crypto currency.

As such I'm hoping that there can I can support trading with the tiniest amount of fees (think 1p per trade). This would all go to server/website maintenance.

Whilst there are a few trading platforms available I feel they are purely private enterprises which seek to profit not support Bitcoin. Im hoping I can create a site which is the very antithesis of Mt Gox.

Aside from low fees and the equally popular and safe escrow transferral method what top 5 items would you like to see in a new trading site?
Forums, live chat etc..

Your feedback is much appreciated.
