Since I have upgraded to 3.0D of my blog software, you may have noticed that unless you had a TypeKey ID, your comments weren't displayed until I approved them. This was to keep blog spam (people posting unrelated comments with commercial links) under control. Jay Allen has just released a beta of MT-Blacklist that filters this spam out, and I have installed it. This means that if you post comments, and they don't trip any of the Bayesian filters, they should instantly appear on the blog. All without signing up for a TypeKey ID. The final version of MT-Blacklist is slated to be included in the next major release of Movable Type (3.1). So enjoy!
