I' ve solved with a little hack, but now I still fighting with JCE....I've read something but not suitable for me...thank's for your help.

Can you explain your little hack

well, I need to have a master site like www.master.com and a slave www.slave.master.com

so I've done a check in index.php of my master template (slave site has the same template) that verify if I'm my url it's from master or slave site and redirect to css master folder or to slave folder...thrn I only change template folder for every site, just to have different layout but the same index, so it's easy to make my changes.

my second step is creating the easiest eay to install and use in my slave sites components quite hostile like JCE ehhe:laugh:
