Thanks liske :)

I've opted for the compilation on the fly just to be sure not to 'forget' to do it later, and also because it's an easy way to store and secure the pages at the same place without too much 'web logistics' : It's only a matter to drop a file in an archive without changing the link to the whole at each post :)

I might have to add a simple link to previous post instead, could be lighter for readers. I take any opinion on the topic :)
