Rules about Multiple Accounts

[Aro2220x]

I have read that dual-boxing (or further) is not allowed. There's even an ip ban thingie if you try and that hits you sometimes if you crash and try to log back in.

However, I was wondering about having multiple accounts. So, instead of having 8 characters on one account, having 4 on two or so forth. You would never be playing more than ONE at a time.

The purpose, then, would be that the accounts could be lent to friends or guildies without compromising your main, or other characters.

Personally, I was wondering if I could help my friend level their account if I get ahead of them since I plan on playing a lot more than she does. Or even if I could make a new account and character on it that would compliment my main that I could have them (or other people) play when I want to show them P99.

Anyway, I wanted to ask before I did anything bad.
Thanks
