PokerEdge on PokerStars

[TStoneMBD]

The PokerEdge forum has been down for me the past few days, so I'm going to post my questions here. I have also searched the past few months for all PokerEdge threads and surprisingly have come to find very little. Is mentioning the word "PokerEdge" the new voodoo?

1) Is PokerEdge against Pokerstars terms and conditions?
2) Has anyone ever had their account closed by Pokerstars due to PokerEdge or any other HUDs?
3) How is PokerEdge's database for Pokerstars games? How many players per table have lengthy statistics from PokerEdge?
4) Are there alot of people from 2p2 using PokerEdge on Pokerstars?
