Sadly I have not visited this site for quite some time and when I received the email asking the question, my first thought was, "Bloody hell, are they still going!"
Like most of you here, I have grown up using Amiga's and my case ended up being in a commercial sense, with a few Amiga A4000's with all the latest hardware that there was at the time, dishing out multimedia projects using Scala, for hotels and conference centres etc. I also used to help out at an Amiga Club in Lancashire, UK where we could pull in 40 odd people every week at one time. Those were the days!. But heh!, thats the past and its time to move on.
I started my computer life using C64's and then on to some of the Amiga range and I now run my own web development and hosting business now. And it's all thanks to Amigas getting me into computing in the first place.
I would bet that the majority of visitors, that do still visit the site, don't necessarily use their Amiga's to visit?. And, I would certainly take the opinion, that you should bring the site into the 21st Century and hope that the small minority of users still maintain an interest. Though retaining the information as an read-only archive, I would say is a must do!
Hell, I would even be willing to give a helping hand. Not recall anyone else offering!
