I have edited the heck out of this post, and it may not be 100% accurate, but I have updated the URLs for the LJ Toolbar, and I think it's working again.
This is a toolbar that you can put on your taskbar, any edge of your monitor, or a standalone window. It's the same kind of toolbar as Quick Launch is, except it's HTML.
It has a username field and a drop-down select field. You simply type the username in question, select an action to perform, and click "Go." In a new window which opens is the information you requested.
The actions as of now are:
Display user's LiveJournal
To Do List
Joule (Who's Friended)
LJ_connect (degrees of separation)
View User's Public Styles
Buy User A Paid Account
I can add any functions anyone would like that can be accessed by some kind of URL constructed with a username in it. For example, http://www.livejournal.com/userinfo.bml?user=USER&mode=full (already implemented).
-Windows 95*, 95 OSR2* 98, 98SE, Me, 2000, XP Home, XP Pro
* = You must have Internet Explorer 4.0 or higher installed.
-Windows will open in Internet Explorer, not another default browser. Sorry.
-You must be connected to the Internet for the toolbar to show up. Dial-up users should probably not bother unless they usually stay dialed-up.
How to get it:
Right-click on your taskbar, select Toolbars -> New Toolbar.
Ignore the list of folders. Instead, type/paste in one of these:
http://www.danpritchard.com/cgi-bin/ljtoolbar-enhanced.pl?you=YOURUSERNAMEHERE&fr=yes http://www.danpritchard.com/cgi-bin/ljtoolbar-enhanced.pl?you=YOURUSERNAMEHERE&fr=nofr=yes if you have a paid account, and fr=no if you don't. "yes" enables a scrolling marquee of your friends' most recent entries. "no" disables it.
Click "OK." You'll see an entry called "LiveJournal Toolbar" on your taskbar. Unlock your taskbar if necessary (Right-click, uncheck "Lock Taskbar") and drag it to where you want it, on or off the taskbar. If you dock it to any edge of the screen it'll be much more compact than if you leave it freestanding. Right-clicking the title of the toolbar will get you some options. I like mine not always on top, not auto hide, at the top of the screen. If you have a lot of screen real-estate you might want it always on top.
Try this out; let me know all your feedback.
