Communicating on the event: blogposts

[NelleV]

We plan for two blogposts:

• [x] Announcing the event. This has to be done at least a month before the event.
• [x] Summary of the event. How it went, lessons learned, etc…
• [ ] Short description of the questionnaire results

Let's add more material here as we think of it. @aliferg can probably help with editing before we post as well!
