For you, Firefox+Greasemonkey People...

[perfectstar]

1. Get Firefox (currently 2.0.0.3)
2. Get GreaseMonkey (currently 0.6.8.x)
3. Get my script (currently 0.9)

This script allows Firefox users to automatically post to their journals in Friends-Only security, and set default screening for comments too.

To change the settings, while at your edit page (and only there), select Tools > Greasemonkey > User script commands > Set _____.

Any questions or suggestions: leave a comment! :-D
