[racket] Planet Packages

There is a planet package that looks like it's author is too busy to
maintain (it has open bugs, and some with unmerged patches, and they are
many months old) that I plan on fixing for my own needs... What is the
proper etiquette for getting a version with my updates into planet?

On github I would do a pull request... but here do I just upload the
package under my username? or is there a way to update the existing
package?

(I'm thinking sending patches to the owner would be ineffective work as
there are some attached to the bugs and they haven't been applied)

(I don't want to annoy the package owner or community, just want to help
out)

Shalom,
Jordan
