Fix issues in presenter protocol and translate.

7.1.1 Change timeline to match this years objectives.

• Section refers to obtaining the attendee list 1-2 weeks in advance of the workshop but that isn't relevant this year because they need to wait for us to supply the code. Should be changed - I think we should just remove the timeline info and say 'Before presentation' and then mention that we will send out the code.
  EDIT: We kind of fixed this by changing the way our email was written to address this discrepancy.

7.1.2 Change email to match this years timelines.

• Should mention that Zoom registration link will be sent AFTER the first email and only after that will they receive a link to the meeting. This isn't clear.

• Need to make sure script is up-to-date and working for all workshops on wiki. Workshop 1 leads to Github instead of automatically downloading.
  EDIT: The wiki is correct for all except Workshop 1. This may be a none issue if we move away from using the wiki in the future.

7.1.3 Maybe we should add a section here explaining the Zoom situation?

• Add section including email to send participants to invite them to Zoom and how to accept their registration by cross-referencing with participant list. OR we just send this info in email but then we should mention that we will.
  EDIT: We kind of fixed this issue by changing our email communication to address this.

8.5 Presenter mode

• Add information on how to use Presenter move while screen sharing by using c + p.

Translate all above sections after fixing

• Update translation of 7.1.1 (See above)

• Update translation of 7.1.2

• Add translation of 7.1.3 IF we add this section (See above)

• Update translation of 8.5

[linley-sherin]

• 7.3 Should add info on how to update attendee list and what to do when you have a legitimate no show (ex. how to contact Helen)
