Playable via Steam?

[BeeSting]

Hello All:

I live in United States and have been wanting to play EB via Alexander.exe. The only way for me to own the expansion was through steam so I forked out another 29 bucks to buy the gold addition.

Now, the questions is:

1. Where do I install EB mod in steam file?
2. And, for those that play EB on Alexander.exe, any suggestions or links on how I can play EB on Steam via Alexander.exe?

Thank you in advance for your help.
