Ruby's WWW::Mechanize

Hi, I've been using Ruby's version of WWW::Mechanize. I really like the
package, but unfortunately I've found a few bugs in it. I've made
patches and tried to contact the author about patching it but I haven't
had any response.

What should I do? I'm not sure what the proper course of action or
proper etiquette is. I think it would be fun to re-implement this
package with Rubyful Soup, but I don't like reinventing the wheel. Not
to mention, what namespace would I use?

I would appreciate any advice I can get. Thank you.
