I haven’t mentioned the plugin system for a while, because I’ve been working on the production version of TightURL rather than the “next” version. However, I’m already starting to use callbacks in the anti-abuse system, which amounts to nascent support for plugins. The first place this is showing up is in the URIBL checks. Since neither SURBL nor URIBL.COM has a stable API (the querying method changes, in URIBL.COM’s case, in undocumented ways in realtime *sigh*) I’m going to implement URIBL support through plugins. This will allow users to upgrade their URIBL plugins as needed without upgrading the rest of TightURL, and it will allow users to add support for additional URIBLs through their own or 3rd party plugins.
