Time to purchase nightfall?

I've played GW and GW:F for about 6 months, and quitted afterwards.
Lately I've had an urge of coming back, to try Nightfall, but I have a few questions.

- If I come back, what would be the best thing to do? Just start on Nightfall and move onto Canthan and Tyria later? (it was Canthan and Tyria right)?

- Also, I already have an account, but it hasn't been used for about a year. Is it still active? Or do I need to unlock it or something? I think I know the e-mail adress but I think I forgot the password.

I can't think of more question atm, I'd like to have some reactions of you guys!

Thanks in avance.

Personally I prefer playing a new character through a campaign before bringing my others over. If you do bring your characters over, I suggest bringing them over from Kaineng center, as the tyria > elona mission is very hard with the lions arch henchmen.

And for your account if you remember the email you should be able to use the password recovery. Apart from getting your password back your account will be just as you left it.

Your account is always there. If the email you used for the account name is no longer a valid contact for you, change the contact email in your account information.

Your existing characters are still there also. So it will be up to you whether you bring one over to NF or start a new one. I also create a new one using the one of the new professions available, but also bring over my main character.
