Thank you for this excellent script.
I encounter following problems:

I installed script for a domain, but I also wish to use other domains. I registered the additional domains in the Admin part > Ok, no problem, I have the wildcards for all this domains, but it's necessary to make moreover files in public_html of each domains ? It'is necessary install script again in each domains? Or just certain files?

Another question:
If one domaine is, for example, yahoo.com

. It is possible to use your script for the Yahoo.com domaine and also use somes services of Yahoo.com ?
Thank you for your answers.
