The Bloglet code didn’t play nice with the WordPress installation, and I didn’t get response to requests for help. Luckily, WordPress has great support options, and there I was able to find the missing information that I needed. For future reference, and for the benefit of WordPress 1.5 users who use Bloglet for subscriptions, here is a working settings format at Bloglet.

weblog title: (name of your site)
weblog url: (url of your site)
weblog id: (leave blank)
username: (leave blank)
password: (leave blank)
server: (yourblog.com/feed/rss)
weblog type: (RSS)
enabled (check)
hide this blog (uncheck)
email setting (set to your liking)

It looks really simple, doesn’t it? But the server information eluded me. I tried an awfully lot of different possibilities…
