Re: two questions about the source code of instance.php
meffee,
I STRONGLY suggest that you checkout branch BRANCH-1-9 from CVS - it's the latest, most stable Galaxia codebase available. 1.10 is under HEAVY development and is not yet suitable for production.
You should also visit workflow.tw.o and thoroughly read the Galaxia Concepts and Manual wiki pages. You will gain a deeper understanding of Galaxia. Regards,
Georger
