If you're looking for the Nik Kershaw site that used to be here, try www.kershaw.net (unofficial) or www.nikkershaw.net (official).
If you're a Kershaw yourself I'd be happy to host a web site for you (for free, as long as it's not too big!) or link to your existing site. You could be http://whatever.kershaw.org or http://www.kershaw.org/whatever
