Finally updated my software, mostly out of necessity! The form spammers were getting to be a pain, so I made some modifications for unobtrusive form-spam catching.
I used a tactic, that doesn't work 100% of the time, but I'd say it's around 90%...and it does yield some false-positives, but you can review any messages it flags as spam. The method I used has an extra text field in the form, which is not displayed via CSS. Since most bots just fill in every possible field with their spamming links, this knows that most "people" would not be filling in this field. If there is content in it, it is considered spam. While you can see where the false-positives would come from, I feel this is less obtrusive to the majority of visitors than using a captcha-like system.
The "Subjects" area now displays the number of articles for a given subject, and the the static pages object (and database table) is now called 'static_pages' instead of just 'pages' (to fix a reserved-word issue with some DBMS systems), and a few other small fixes.
For complete details, see the CHANGELOG.
The ctBlog demo has also been updated to version 0.7.
