Ahh.  Wasn&#x27;t aware of that.  I found a screenshot, and it&#x27;s an odd, non-obvious way to allow tipping:<p><a href="http:&#x2F;&#x2F;www.sarahdoody.com&#x2F;wp-content&#x2F;uploads&#x2F;2014&#x2F;03&#x2F;lyft-ux.png" rel="nofollow">http:&#x2F;&#x2F;www.sarahdoody.com&#x2F;wp-content&#x2F;uploads&#x2F;2014&#x2F;03&#x2F;lyft-ux...</a><p>I wonder how much that keeps it from being used.
