Questions about vBulletin
 

I am looking to set up a membership website.

1. Is vbulletin easy to set up?
2. Can vBulletin be attached/intergrated in the website I have got?
3. Is it possible to make the membership area look the same as your own website
or is it possible to have a 'skin' or theme made so that it looks the same?
4. Is it safe and secure?

Probably have some more questions which I can't think off.
