The bounty idea mentioned by readheadedrod sounds like a good idea, as the successful developer would not be paid until the module was proven to work as intended. However, for the sake of Xoops, I would make it a condition that the developer can have the bounty money as reward for their hard work, but the finished module would have to be free GPL and made available for all Xoops users to benefit from.
Of course only contributors to the bounty would be able to beta test, as at some point they would be testing late RCs that would be more or less fully working. Plus, whoever managed the finances would need to have a protocol in place to deal with a situation where there were perhaps 20 contributors and only 18 were happy with the finished module.
Personally I think the competition would be great. The winner is the person that delivers a module that is 100% working and 100% bug free - exactly what Xoops needs IMHO.
A thread is for life. Not just for Christmas.
