I have a 2005 and a 2007 account I have in the closet kind of.
I list a few things a month, buy some things, watch some things etc.
Has to be treated like new since it sat for a long time.
Use it wisely and slowly.
Issue with being a family members also. I am not for using a family members account because if you screw up and cost them the account and they want to use it later you will be the blame. Not a good situation to be in.
And you never know when someone needs to use that ebay account either.
