Blogging Accessories: I’m not planning on downloading or subscribing to any of them, but you bloggers out there might find them useful or interesting:
BlogRolling: Remote service which maintains your list of blog links so you don’t have to worry about the HTML. Generates code for you to cut and paste into your Blogger template.
Posterchild: PHP-based inline commenting system, similar to BlogKomm. Server-side only, so Blogspot bloggers can’t use it. DotComments is still around if you want to use that. (Also server-side.)
pMachine: PHP/MySQL blogging engine. Lots of features.
