I have found items that belonged to someone that went inactive and has been for 4 months now. I picked them up and have equipped them but how can these items become made over to me so I would technically own them, so I could sell them or what not?
The only way to transfer ownership is for the current owner to make them over. Until such a time [likely with combat] that it is possible to hijack assets, you will have to just consider yourself lucky to have come across unused items.
I dare you to make less sense.
Are you a newbie, or do you have access to newbies?
