A few points:
The brown/orange/blue graphic at the top of the main page looks a bit uncool 70s. What was wrong with the old blue logo? In fact, the main page doesn't even have a heading - there nothing to tell new visitors they've reached amiga.org, unless they look in the window's titlebar.
When I was typing a long comment in over the space of an hour (was doing other stuff too), when I clicked submit I found it had logged me out! There was no way of getting back the message I was typing either. The old site used to leave me logged in all day.
The fonts on all the pages are far too big, and many are different styles - on some pages there is Arial mixed in with Times New Roman. For example, on this "post reply" page the "Disable Smiley", "Attach Signature, "
"Notify me of new posts in this thread" checkbox labels are in different fonts to the labels on the form buttons.
The quote/url/link icons are not obvious what they do.
There is a 0.5cm black border around the edge of the page, when a page is loading (before any content appears) the page is all black. The change in colour is a bit disconcerting.
The site is too wide for 800x600 screen res. AW.net and MZ, other XOOPS sites look fine with 800x600.
Just trying to be constructive.... sorry if there're any mistakes in this - I had to speed-type it in case it logs me out again!
