Since the user contributed "how to secure gallery2" article was only about
one specific case and only about a small part, i've written a larger
document dedicated to Gallery 2 Security.
Feel free to review, reorganize and/or extend.
It's already linked in the howto section and i'm glad i can point users to
this document instead of reiterating the same stuff over and over again.
The user contributed article is now just a small link in the new Security
