Forum update
The forum https://forum.duniter.org is presently under maintenance, we try to stop using the SparkPost mailing service, which is way too much restrictive.
We will update this post as soon as the forum is available again.
Edit on October 11th 2016: The forum is still available, but be warned: we can interrput it at any moment to process our maintenance scripts.
Edit on October 15th 2016: Maintenance is over!
