To successfully claim your prize you need to follow a few rules:

1. All code submitted for a bounty must be without any known intellectual property limitations. Furthermore, it must be submitted under the same license as the application to which it will be applied (for example, GPL for IMP, LGPL for Horde).
2. The code must be accepted and committed into the development branch by the module’s maintainers before any prize will be awarded.
3. In the case of multiple submissions for a single bounty, the judging panel will select and award the highest quality one.
4. Group submissions must designate a lead person who will submit the claim on behalf of the group.
5. All bounty awards or rejections are at the sole discretion of the judging panel.

Once you have submitted your code and it has been accepted into CVS, just let the developers who handled the patch know that you’re claiming the bounty. Prizes will be paid using PayPal.
