Thanks. Where'd you manage to dig that up? Either way, link is broken.
Creating a new applet is very easy:
1: Press create
2: Press the + next to THIS
3: Search for Twitter. Click New Tweet By specific user
4: Press the + next to THAT
5: Search Groupme
6: select Post a Message to a Group
7: Select the group of your choice
8: (optional:) remove all extras from the message box - to get as much of the tweet as possible.
All done!
