I just released my first "real" style (meaning not being an EZ style).
It forwards your notifications directly to Twitter and makes a tweet
there. Just download the package, run the setup file and restart Snarl
if it had already running.
https://sourceforge.net/projects/mozillasnarls/files/Tweet%20it/Setup-SnarlStyleTweetIt.exe/download
When you now use the new style "Tweet it" (which should be in the list
of styles now) it will as you to authorize this style with Twitter (this
in only needed on first use and will pop up automatically on first use).
I have tested the style and the setup on both Windows XP SP3 and Windows
7 but would be happy about some feedback if this is running on your
machine too.
