Yeah I keep a doc with all my accounts for all L2's private/official lol, started it like like 2009 when I noticed I started to forget them, even kept a few of ones friends shared on servers over the years, and ended up helping buddies remember their accounts because of it LOL.
My only fear at the moment is trying to level here, I'll probably only have the 1 char, and with very few people at low levels (I saw no-one when I logged yesterday at my lvl range) be hard to lvl up without buffs, unless I try to go WC main or something.
