Nostalrius Begins - Quality wow vanilla realm (1.12)

I wanna start playing with horde... Is it allowed to send money from my alliance character to my horde character?

To be more specific..
Is it allowed to send silver to my horde character by mail.

You can't send mails cross-faction.

The only way you can transfer gold is using the neutral auction house, which requires two accounts to do so, and also a higher auction fee (15%?). This approach is legal.

You can also arrange a gold trade with someone on the opposite faction. (I've checked with a GM.)

*As long as it's on the same server.

Yes you can do this.To many people can't give you an answer because they don't know how to do it.
What you'll need is a friend,the gold of course and a crappy white or grey item.Also you need the Neutral AH.
