I would like Amibay to keep a simple design. I often browse the forum with my Amiga (AGA or RTG) and enjoy the full IBrowse compatibility so far.
If it is the retrocomputer trading post, keep it retrocompatible.
No need for fancy html thingies.
Let me second this BIG time. I often access Amibay from my various mobile devices and it always makes me happy how clean and fast the front page (and in fact the rest of the site) is. The last thing we need is some fancy frontpage etc..
Over the years several of my favorite sites on the net 'upgraded' themselves, and I hated the new design every single time. Call me conservative but I like pages where the space is well used, as opposed to some 'great look' where buttons take up half a page and everything is pulled apart.
