Can vBulletin do user flags? (and a couple other questions)

[theothersully]

Hello,

First post. I'm trying to determine vBulletin vs phpBB. I'm leaning toward vBulletin, but I have some questions:

1) Does vBulletin support any kind of "user flag" system, similar to what Craigslist uses? You know... allowing users to flag down posts they don't like?

2) Does vB have the ability to have a single sign on for multiple forums?

3) Is all the data vB writes in MySQL clear text? As in... if I need to reach in and read data from a table in MySQL, is it there for me to see? Data such as the list of users?


Thanks in advance, everyone. I hope to be on this forum a lot more actively soon... if vB can do some of the above.

PS: In case any vB staff answers, I am looking at purchasing several licenses.
