Scratch

I've had that happen when I try to search some of my friends. Just tell them to type scratch.mit.edu/users/bellabimba into the url bar, then your stuff should come up.

http://scratch.mit.edu/users/bellabimba is your user page.  I think that because you have only made 1 project, your page will not come up when you search for it.  It almost always happens.  If you like, you can use this post as a reference for your friends to see your user page.  I hope this helps. 

The search isn't perfect - in fact, Google powers the search engine, and finds websites purely be scouting the internet for links. If nothing links to your page, Google can't find it without searching a little deeper. It also takes a few days for things to show up in the search engine.

Furthermore, just copy and paste the URL of your user page and they should be able to get there just fine.
