Offering to maintain Search Log

The protocol for becoming a maintainer (if the owner is unresponsive) says you should leave your offer in the project's issue queue (i.e. do not move it here. Instead, create a child issue to get assistance from ownership administrators). By having your offer in the project's issue queue, you make sure that the project's current owner and most active users see your application for maintainership and can comment on it. Quote:

If the owner is not responsive, create a new issue in Drupal.org project ownership issue queue, but leave the original support request in place, for the present owner to see when he/she monitors the issue queue.

I suggest you move this one back and and create a child issue here.

Since the project has opted into security coverage, and you don't have the vetted role, moderators will not add you as maintainer/co-maintainer of the project. Or the project owner adds you as maintainer/co-maintainer, or you need to apply to get the vetted role.
