This topic was brought up in the triage meeting today. Numpy is seeing a huge surge in the number of PRs (current open PRs: 253) which could means two things: 1. Increase in volume of incoming PRs 2. Not enough reviewers to review the PRs. 

One thing that was discussed in the meeting was to add a stale label : "61 - Stale" which has already been added by Sebastian. 

The community needs some help here and I think you can help irrespective of your level of experience with the numpy codebase:

1. Experienced numpy developers - To help review PRs for the areas they are already familiar with.

2. New contributors - Can help tag a stale PR or summarizing a long running discussing and next or reviewing PRs/triaging issues (for example DOC PRs should be a good starting point).

Numpy community has been generous with Triage access and if you are interested in Triaging PRs or Issues, please reply on this thread and a committer should probably be able to help.

I welcome more inputs on what we should do to reduce the number of open PRs, and what would help increase contributors or for contributors to do more reviews.
