If you're a plugin or theme developer and you're wondering whether it's worth the effort tagging some issues — it is. We did last year and ended up with quite a few new contributors closing issues.

We have #hacktoberfest issues tagged for both our Charitable plugin and Reach theme:

- https://github.com/Charitable/Charitable/issues?q=is%3Aopen+is%3Aissue+label%3Ahacktoberfest
- https://github.com/Charitable/Reach/issues?q=is%3Aopen+is%3Aissue+label%3Ahacktoberfest

A bunch of really low-hanging fruit there (some have the solution right there in the comments).
