I feel it's a bad idea that the maintener should have two accounts!
But it could be a good idea if addition he makes are tracked the same way as other users.
For that, does he need to (and can he) create a stash, and a contribution (that he would check himself) ?
Would there be a (better, easy) way to see details of recent integrated
language string, to be able to review them, and correct them if needed?
We'd really appreciate that feature: in the Basque language pack nowadays we're several contributors translating strings, and there is only one maintainer approving them. We're thinking on changing this process and upgrading two contributors to maintainers in order to share out the work, but we want him to remain being the lead maintainer. To achieve that, it would be great if he could see and easilly review all maintainers' changes.
