Thanks. I've been using a modified release of phpnuke + win-apache in order to understand how the mod_rewrite works on my computer. I found pretty difficult to manage it; so my questions are 2:
1. is there any free content management php+mysql platform (easier to modify and even more important faster) you may suggest.
2. if I register a 3rd level domain, can I use the mod_rewrite to make links SE friendly? (I used the .htaccess file to do it, but maybe some changes in the apache scripts are needed)
