I noticed you have like, shared hosting, vps etc, but do you think it would be useful having a Green Hosting forum, to seperate ones from good eco and bad eco.

definitely. i'd only want to host with the bad ones, so i'd
not then be wasting my time checking out supposedly 'green' ones.

We have a sub-forum for discussing green hosting: http://www.webhostingtalk.com/forumdisplay.php?f=157

If there is substantial traffic in that sub-forum, it may make it up to the main forums one day.
