My b2evolution Version: 4.0

Hi guys! I am new to the b2e forums and blogs. I noticed these forums used by a christian radio station and that's what made me fall in love with these blogs. I have a few questions though.

Is it possible to do the following:

1: Post a Facebook login system on any of my blogs using JavaScript SDK? Which allows users to log in with Facebook if they have a Facebook account. Basically what it does is, if put the code for the login button on my blog, it will force the blog to be totally locked down unless someone logs in with a Facebook account. I wanna do do this for security reasons and because a lot of my christian family are on Facebook.

2: Is it possible to sync posts across 5 blogs out of 10. Not the entire 10 blogs but just the 1st 5. The other 5 is for tech support, prayer requests, photo logs. and much more.

3: Also is my blogs able to post java script links, aadds, and buttons or even flash onto my blog?

Sorry If I have not found an answer to these questions myself. I have been working for a couple days on trying to get this system to work by figuring out how to install the blog and as well as trying to find a decent free web host till the 1st of the month. I got the blog installed finally and I got the control panel opened up and looking through the settings. there's a lot of stuff here. This is unbelievable. But anyways any feedback is welcomed. Thank you and God Bless.
