At the PPUK conference yesterday, Rick Falkvinge explained PPSE's "Three Pirate Rule". In the finest Pirate tradition, we're copying it.
According to the Three Pirate Rule, if three party members agree that an idea is a good one, they don't need any further "permission" to get on and make it happen as an "official" PPUK activity.
There are only three exceptions to the Three Pirate Rule:
Don't do anything illegal.
You can't allocate party funds (although you can ask for them).
You can't do anything in Northern Ireland, due to current law. If you're interested in doing stuff in Northern Ireland, please contact the NEC for more info.
The NEC receives a lot of requests from members to grant some sort of Official Stamp of Officialness to various initiatives. Hopefully, adopting this rule will make it unnecessary for people to make this sort of request.
