I'm not sure what you meant there. Can you give me more explanation please?
What I do understand right now is either
-> Participants does PM us the answers then we reply.
-> We are PMing the participants with some sort of directives.
Personally I'm not exactly sure how it would work. Let me explain; usually because when we are doing an activity (especially those mentionned), unless it's completely private, people should be able to see what the others have wrote, and it did always worked well, so I would really suggest doing it this way, if it's alright with you. I remembered doing it this way with my activity, so if you need some visions of how it would work, the best would be to look here, then you can give me your decision with more explanations of how you would made it work then I might see what you meant more.
By the way, I added a new topic about how I did the banner and how I should do the presentation if you want to look at it, we have to do some ajustments, and then I guess the board can be opened today, when everything will be decided. We'll be able to discuss about it in that said topic. I will then start December 1st with the first activity we said about. Sounds good?
