Wanted to try BML. I installed it but I don't have it running yet and I think it is a question of configuration on the Apache server. I have a Apache with suexec and although that is important for security reasons is really a TERRIBELLY headache!
But I manage to know how to use .htaccess files, already.
So the HTML files I'm building for the administrative site for each virtual server will be probabilly built in 4th-HTML.
And now, really; i'm going to have some rest.
