@Tabris32:
1. You must talk to Metzger if you want to be able to enslave NPCs. However, you can still (without being a slaver) use "Rope" on brahmin, which will tame them. Also, use rope on negative-HP NPCs to enslave them, such as NPCs in Trapper encounters, once you become a slaver.
2. Sending money to another account means the other number in that city. You can't transfer money to a different city, only to the account in the same city, which most likely, isn't your same account number.
3. You are not allowed to dual-log (use two+ characters online at the same time), so that doesn't even matter.
