Possible Job Switch?

I was all prepared to jump right back in to Outlook for the third time this summer. Then, two days ago the GM of Frontpage messaged me and asked me to work for him this summer instead of Outlook.

I was a little shocked and flattered, to say the least!

I don't really know anything about the project for Sharepoint they want me to work on, nor do I know anything about the Outlook project. I'm a little worried about just abandoning my old group. A) I love the group. I love the people, and I love the job. B) They only have 4 interns, and they'd be losing 1.

So, I've got some things to think about...
