RubyGems.org now supports Gittip
You can now link to your Gittip account from your RubyGems profile page.
Gittip is a way to give small weekly cash gifts to people you love and are inspired by. You can find more details on the Gittip about page. If you don’t have a Gittip account you can quickly create one by clicking the sign-in button in the top-right corner and logging in through Twitter, Github or Bitbucket. You can also create a Gittip account for an organization.
After you’ve signed in, you can edit your RubyGems profile to include your Gittip username.
