Yet another update (03/17): Now works with reclaimvote and brief invocations.

Update: Worked out a few issues and included dupeof, doublepromote and notdead invocations.

While browsing through the Sift Talk section I saw something gorillaman said:

"I'd ignore siftbot if it would actually make the comment disappear entirely, rather than just the text."

Since the siftbot comments don't count towards the total number of comments anymore and the affirmation messages siftbot posts after each invocation can really clutter up the comments section of a thread I wrote this script. It merges the invocating comment with the affirmation message from siftbot, making it look a little more organized. You'll have to disable the script if you want to upvote the merged siftbot messages or see the corresponding links for siftbot (profile, timestamp, etc.).

You need FireFox and the GreaseMonkey extension for this to work. If you don't like the colors you can easily change them by modifying the color and image variables at lines 10 to 12 in the script.
