Hi Damian, you know I love the site or I wouldn't be here so much - in fact I am thinking of setting up a group "Sydney Cyclists Anonymous" where we can go and confess our addiction and see if a Higher Power can give us the strength to control the time we spend here!
However, just a couple of points:
I think I preferred the avatars on the left on the Main page.....or could you let me know what those other symbols mean. You might have but it didn't hit me in the face like a hammer which is what I need to see something. Also, I agee with Marianne below. I am pretty clueless with such things and the Invite process got confusing for me and I am sure I made a few mistakes before I got it.
I still find it hard to navigate the long threads too. The most recent don't always go on the end (depending on who people reply to) so if you see that 4 people have replied to something in the last 15 minutes, it is hard to find them sometimes.
Also, it would be good to have the tabs at the bottom of the page too - at least the "Main" one.
sounds slightly worrying, but I don' t think it's the case. Still, I've thought a few times about what it would take to move from the ning platform to something else (probably something I'd do as an open source platform).
If you were to consider porting to a new (developed) piece of software, why not utilise something like Joomla, with a little tweaking and some plugins, you could have something very similar to the current site
