I played this game back when I was in 5th grade

Back when that Floating Citadel was just released? (Like 3 years before that came out?)

I've been trying to figure out all my old login information, but I can't seem to find it. Do they delete inactive accounts after a certain amount of time?

Nope. I didn't get on for years and I got back on just fine.

i think they do randomly. My old account, now its like 9 years old, is still there, but my brothers is gone for some reason. sucks too cause the email that was used on the account is gone, and TNT knows that, so they told me that there is no way i can get the account back. lol. No idea if anything is even on it, but if there is, its gone forever >.>

they sometimes delete it...my account back from 1999 was deleted...

my oldest account from 2003 is still there i'm looking at it right now but i have no clue the account info, password, old email

so i made another in 2008
my account now is 39 mons

still wish i could access the old account though..
