I'm not sure if this blog supports it, but it's not beyond the realms of possibility for someone to add one of those "type in the numbers you see in the picture" thingies that you often get when you register for sites (e.g. hotmail lol). In fact I'm certain you could do it. Unfortunately, it then raises an important accessibility issue which is something I know you're looking at improving (although to be fair there's not a huge amount necessary on this site to make it nicely screen-reader friendly at a glance!). Maybe you could offer this system and a registration system in parallel to provide a couple of ways of allowing people to post comments? I'm sure someone with more time and savvy of this blog could do some homework for you if you haven't the time yourself... /al from djstalkerdotcom :o)
