You used to be able to view PhilInfo for free on the LaPoste website but not any more. They are now charging 23€ for a one year subscription (I think it was one year, have to check). I think this is rather unfortunate for collectors. PhilInfo is a magazine put out monthly by LaPoste providing a few articles with technical details and images for all issues that month including those from the territories.
I found the monthly heads-up rather useful but not enough for 23€. Ironically, to subscribe to the online magazine, you have to print out a order form, fill it in and mail it back to them to receive your user name and password.
