I love my 1 day's worth of experience... some quick question

1. When I create a sub view I don't have the ability to sort the columns on the fly the way I do with the parent view. Am I missing something?

2. If the data I want to post and share privately needs to be secured how to I know that it is such? What standards, auditing/anti-hacking, etc. assurances are there? I love the "free" and easy to use aspect. But is it 100% secure???
