There should be specific sections.
There should be a section for unexpanded classic Amigas, a section for classic Amigas which have been upgraded with PPC, PCI, and graphics cards etc, a section for Amithlon / UAE, a section for Classic Amigas running Linux (68k or APUS), a section for A1 running Linux, a section for Pegasos running MorphOS, a section for Pegasos running Linux, a section for AROS, and probably some other sections too.
And you should have to prove that you own / use one of the systems before you are allowed to post in a particular section (maybe take a picture, and send it along with the output from whichamiga, to one of the moderators for verification).
This would stop all the bickering and flaming as only AROS people would post to the AROS section, ony MorphOS people would post to the MorphOS section, etc. so there would be no "My PPC Amiga is better than your UAE" or "My Pegasos is better than your A1" etc as the only people posting in the same sections as you have the same computer.
