One option would be to suggest that each interested participant open the SciPy issues and PRs list, and then sub-select based on the `label` corresponding to a submodule they might be interested in. That way people will gravitate toward domains where they have knowledge and feel comfortable, and it cuts down on the number of issues they need to look at (because we have so many).

And of course there is also the "good first issue" label, which can be useful even if it's inconsistently applied.

As for any specific issues, I can't think of any offhand.
