Write a dialog with this premise "Jim will create two deadline alerts: one for the selection of the topic and one for posting an article on the blog. He will also make editable notes of both and share them with everyone.".
Miriam: Make a note of the date of our next blog post deadline, will you?
Jim: Sure. It's the 10th, right?
Miriam: Yes, every month we should publish at least one post by that date.
Jim: No problem. I'm making it a regular deadline alert.
Miriam: Good. then we have no excuses!
Jim: Right.
Miriam: We just need to come up with the topics.
Jim: Exactly.
Miriam: Probably we should make another deadline around the first of the month to decide on the topic.
Jim: That would work. 
Miriam: Gives us plenty of time for collaboration.
Jim: Yes.
Miriam: Great. Make notes of both and share it with everyone, let them edit so topics can be suggested in the notes field.
Jim: Will do.
Miriam: Thanks!
