Offering to maintain RSVP List [#3234521]

RSVP List has been automatically opened to new maintainer applications, as it will otherwise become unsupported with the end of life of Drupal 8 on 2 Nov, 2021.
This is an adaptation of our existing process for transferring project maintainership.

After the standard 14-day waiting period from this issue being opened, if an existing maintainer has not closed it, this project is eligible for new maintainers, without necessarily waiting for existing maintainers’ approval.

Next steps:

An existing maintainer may close this issue and opt out of this accelerated process.
A prospective new maintainer can take this issue after the 14 day window has
elapsed and take the following steps to be added as a maintainer:
- Comment here explaining why you would like to maintain the module.
- If the project is opted in to security coverage, confirm that you have previously received security coverage opt-in permission.
- If an existing maintainer has not commented, move the issue to the Drupal.org Project Ownership queue, by editing the “Project” field on this issue.
The Drupal.org site moderators will review the issue, and if it meets the requirements can grant you maintainer access.
