"Maybe"/"Interested" role

Currently, the only way to keep track of a party you have not committed to attending is to either bookmark the page (and remember to come back to it) or leave it open in a tab. If I don’t know whether I can come a party yet, sometimes this means that I lose track of it (especially when switching devices). An option to flag myself as interested in attending, but not able to commit yet, could put the party on my Signed Up list and mean I could easily find it again.

This could also apply for External parties, allowing users to keep tabs on them until they have time/device access to follow the signup steps.

If recurring parties are implemented in the future, this would also allow players who can attend for only some of the scheduled times to keep track of the party through the recurrences when they cannot attend.

Currently, hosts could probably finagle this with the existing featureset by adding a second activity with a custom signup option (which would also be cool, if widely adopted), but having a dedicated option a host can enable for their party might be useful.
