Went to Blogger to see whether they have following capabilities. Yet, discovered that there seems to be no way to email them. Does anyone know one?

My list of cababilities I would like to have on my site; need to know whether Blogger has:

1. am concerned that between time I sign up for blog and time I register, someone else will grab domain name and register. Does anyone know how to register (and pay for) my own domain name thru Blogger @ same time that I set up blog?

2. people can click on button and make their home pg.
3. can send out newsletters
4. ability to work on multiple browsers well
5. ability to have alternating photos (one fades into another every few seconds)
6. videos/podcasts
7. scrolling quotes on top of pg.
8. ability. to list many blogs and 1 line teaser
9. ability. to only have people comment who have registered.
10. ability. to tailor registration ?
11.visitors can't comment until registered.
12. formatted for adsense/merchant affiliate ads
13. interface w/facebook/linked-in/you-tube etc.

any input welcome.

Gracias!
