Comment: I've upgraded, I love it, but I've got some questions

" Are there any example extensions which I can see to learn from, or documentation about creating extensions for YACS? "

The Internet has some non-written rules that everybody is supposed to enforce. One is that every CMS should have a plugin system. Well, maybe YACS departs from the main stream since it does not have such a thing.

IMHO plugins have the same characteristics than sand boxes: boundaries are clearly defined (i.e., programmers' job to create a plugin is quite easy), and boundaries are enforced (i.e., programmers may have to sweat a lot to implement not-foreseen features).

Can YACS be extended? Of course, it has even been designed for that. Here are some options for courageous, motivated and talented programmers as you are:

• For little things, consider to include your code into existing scripts. Please use the query form, or post an article with attached files, and I will integrate everything into the next release, naming you as one of YACS authors.

• To specialize pages you can implement the overlay interface. This is a kind of plugin interface that let you leverage on articles. Check overlays/overlay.php for more information. Also consider overlays/recipe.php as a practical experience of it.

• For huge things, create a new subdirectory, and drop your scripts in it. Bind these scripts to existing ones with hooks, where applicable. Check control/scan.php for more information on hooks.

• Regarding the geographical stuff, I have started to develop some scripts on my own. For example, my user profile (Bernard Paques) has a link to a location, and that location may be displayed in a map. The idea is that a page, or an user can be attached to any number of locations. Also, other scripts, maybe yours, could use this information to provide additional services. Please feel free to expand on that.
