Joining Trade Chat While Outside CityFollow

Simple question, really. How do I join city trade chat while I'm in, say, EPL?

I quite often relog to do the odd enchant for a tip and it's handy to listen in.

Or is this not possible any more?

Those gold seller alts can either join zone channels they aren't in or send messages to zone channels they aren't in, one of those two. If it's the first one, then there is some way for you to join trade, but it may be considered a hack or exploit, I dunno. If it's the second one, which is how I think they do it, then you're out of luck.

Overall, I think it can't be done.

You cannot join the trade chat outside of cities anymore. The gold sellers use either a hack or an exploit to spread their advertisements.

Oddly, you can join the trade channel when you are in an opposing faction's city, ie. when I'm stealthing around Orgrimmar or Undercity.
