Hey I was wondering if there was x amount of time of being absent without loosing your account, or if the account will stay regardless of time gone... it's just everything will still continue (ie horse aging) while your gone?

Accounts do eventually delete. It happens after 6 months for an account that's always been free and after 2 years for an upgraded one/an account that was once upgraded. However, things will still continue on your account, regardless of whether you're active or not, until you hit that tume limit.

Usually the game sends you an email before the account is due to delete, so you will get a fair warning regardless.
