USA and Central merica sites

I want to create a English version of my site , so maybe I think use a subdomain ? and made a new joomla and import HIKA into , because I need the same Hika . what you think , will be us.miicards.com and the main site is miicards.com

thanks so much

You could have several languages on one website you don't need several websites if you use joomla 1.5 by using joomfish. For 1.7, joomfish is not yet released (there was a first developer release made recently) so you would indeed have to duplicate the website.

Thanks , the thing is that not all will be translate like banners -adds, and also some prices will be different, so is the same company focus on another market using a subdomain name .

ok, so having a copy is indeed a good idea.

Do I need another HIKA licensed if is inside the same domain , I have uno.com, I wil use: 2.uno.com , I want to import the hika to the sub domain and change the prices etc... so I dont have to create all products again , I can use the joomfish for that translation also.

No problem.
You can use joomfish yes.
