Damn. I love YouTipIt, and when I seen you suggest it, it made me remember they do have a function to start a tip jar for someone else, but then I seen this.
Want to tip someone who is not on Youtipit?
You can create a tipit for a person you think should receive tips but is not a member of Youtipit yet. Its easy, just create an Escrow tipit for them. All you need is thier Facebook profile URL and some bitcoins in your Youtipit account to tip them with. Once the tipit is created other people will be able to tip them and the person can claim the tipit at any time by registering with thier facebook account.
