Hi Javier,
Yeah it's me again. I notice the following error: When you add more than one whois module to a page and you enter the domain and click search in one module, the other module gives an error (validation error). This means that I'm restricted only to one whois on a page. In the future, if my pages are really big then I would like to add more than one to a page.
Regards
