So why did the domain/URL change anyhow?

[genphreak]

I just remember noticing a year or two back that there were outages and name server changes... eventually I stumbled through aliased forwards finding nothing. I eventiually looked up the zone records to find bimmernut.com (not online properly) and then a few days later the forum was back on that URL. I know that Ed had www.bimmernut.com for ages, but

Why did the forum change URL to bimmernut.com?
