+??? Who can be registered as PI (Primary Investigator) at Baobab?
+!!!
+  * Anyone with an ISIs account (even an external one) with a fairly long validity period: teachers rather than assistants.
+  * Someone who knows the users they are going to invite. All their users will be under their responsibility.
+  * Someone who knows the service(s) for which they will be inviting outsiders. HPC in this case
+  * Person responsible for teaching or research (therefore responsible for the data generated and able to know what to do with it when a user leaves).
