Finally managed to install it as my first line of defence against the never-ending onslaught of spam. It’s done the job very well indeed – no spam as far as I can see since it was deployed.
Why did it take me so long? Well, I’ve got a tendency just to tinker along with fixing and trying things on the site. Movable Type seems to be one long process of tinkering as I add widgets and so on. If I could get the Action Streams plugin to work properly it would solve that to some extent.
The other dilemma I’m facing is whether to change the layout of the site to three column to accomodate a wider site and more content blocks. It’s a time-consuming piece of work to attempt for a site which gets relatively little traffic and which I’ve still yet to figure out what purpose it serves. Any easy way to do it?
