Hello,
I'm looking for advice, best practices etc. for a setup with multiple sites that I will try to describe here.
First: how it looks now. I am the webmaster of some 7 sites, that have all come into live in an independent way, and they are all produced with different means. One of them is drupal(gardens), one is written in html/css, one is made with iWeb for the Mac. What they have in common is that they are all about music, mostly centered around one city, and that I am involved with all of them, sometimes as a musician, sometimes as a concert organiser, ... The other sites are either from groups (for instance an orchestra) I work for, from concert organisations I work for (and that programm my groups or me), or from friends who are also involved in one or more of these projects/organisations/groups etc.
To make this more concrete:
I have my personal website: www.tomdeneckere.be
I have my orchestra website: www.kamerorkest-arcenciel.be
I have a website for my music production company: www.firstact.be
I also run the site for an umbrella organisation www.muziekarchipel.be, which 'umbrellas' some music organisations and music groups and individual musicians in Aalst, my home town.
This organisation is best known for a festival it organizes, and for which they have another site: www.mazzic.be
