You can create issues to describe problems you have with the presidium. This can be used for anything related to the duties of the presidium.
Furthermore you can use this to ask the presidium to do something (basically a "feature" wish). The last thing you can do is asking the presidium for information.
The repository will also be used to deposit the raw, edited and approved versions of the protocols in their non-compiled form. That way you can comment on the edited protocols before the next plenary session, which reduces the time to approval.
The summaries will also be available in their LaTeX form.
The wiki will be used to showcase the general roadmap plan of the presidium. You want to know what the guiding principles of the presidium are? Look there.
