About a year and half ago, the CPAN community started to join Gratipay (formerly known as gittip), possibly under the influence of this post and that mashup.

Since then, laws and regulations have caught up with Gratipay, forcing them to radically change their model (there's something to be said about doing a little bit of bibliography/research on the problem area before diving into the code).

So if you joined Gratipay at that time, and received some tips, you should read this.
