gRegorDo you still only add the etherpad to the event page shortly before the event? Might be better to include it initially, then clone the events and change the dates. I think that's how GWG does HWC Pacific
gRegorFewer parameters and ideally all of the information needed can be extracted from the etherpad (if we also start adding the events.indieweb.org event link in the etherpad)
sknebelso the slug parameter is only needed if it doesnt know the events.indieweb.org link - which it right now doesnt know if you give it an etherpad link
gRegorI guess I don't have a strong preference if it works, but it feels more intuitive to me to create an archive of an etherpad, I would use that URL. Some inferring needs to happen in either case.
[tantek]to me the etherpad link makes more sense as a parameter because it's literally the direct object of (and has the contents of) what you want to "archive"
[tantek]the creation of the etherpad also requires (in practice) choosing a slug at the time of creation (rather than later at the time of archiving) so it lowers the labor to archive, which is the right place to optimize
