killfile is super awesome, yay!

I'm pasting in Xtina's additional code for FetLife forums here, since I can't leave a comment:

* Search in the script for the string function pandagonNewScenario. After that function block, add this code block:

function fetScenario() {
                    return {
                        commenttopxpath: "//div[contains(@class,'group_comment')]",
                        sigbit: "./*[contains(@class,'span-14')]/div[@class='quiet']",
                        precedingBit: '<a href="/users/[0-9]*">',
                        followingBit: '</a> responded .*',
                        __proto__:wordpressScenario()
                    };
                }

* Next, search for the string ravelry:[{scenario. After that line, add this line:

fetlife:[{scenario:fetScenario,hrefpat:"[^/]*//[^/]*/groups/[0-9]*/group_posts/"}],

* Save and close, then reload a fetlife groups post, hooray!
