[Cartoweb-users] admin zone - new plugin?

[wochter]

Hello list,
I'd like to manage my cartoweb users.
I have written small php script which can do it.
But I need implement it into cartoweb.
Can I take the phpsession, or I have to write new plugin?
I'm beginner to object oriented php and I don't understand cartoweb code
very much. I have read the doc about new plugin creation, but I still
don't know how to do it :-(
Is there any empty plugin to download?
How can I start please?

Thanks for any advice.
