Script Summary: Changes the link on your favorites' comments page from "Commented on 'this post'" to the name of author of the journal entry.
The primary function is to change the link on your favorites' comments page from "Commented on this post" to "Commented on [author of the journal entry]". Also works on your own comments page. This just makes it easier to see where you're going.
Sometimes your favorites, for whatever reason, insist on commenting on a particularly awful user's journal all the time. This script can filter out comments to journals you don't like.
Use the GreaseMonkey "User Script Commands" menu (right click the monkey icon) and go to "Setup More Relevant journal filtering". It will ask you which user's journals you want to ignore (and how many comments your favorites have to make to them until you will begrudgingly take a look). When your favorites comment to these journals, their comments will be removed from your comments page. Next time blaidd comments on sethwantsagirl's journal, you won't even see it. Phew.
