Well. This is probably the most trouble I've had converting a site. Ever. I've moved from a database back-end (using MySQL with a PHP front end to extract the posts/links/whatever) to nothing but text files. A small (but fairly complex) script called 'blosxom' extracts the contents of a directory structure and all the *.txt files in it, and creates this website.
One can hope that I won't be required to switch to anything else any time soon.
Anywho, posting to this one is as easy as typing in a text file, and I won't have any problem with spammers using the comments on my site. ;)
Duncan, I'll be contacting you separately with instructions on how to post.
