Hi list, My tag_question_user join table is not currently a full-blown model. It doesn''t have a primary key - just tag_id, question_id, and user_id.

It can be quite hard to manage a pool of 40-50 VMs without informations about the OS running, the contact (which is the only one to know when the vm can really be destroyed) or an End Of Life date.
