Hi! Now, I know Towny is still in beta and I thought if the Towny server is going to get updated, why not add a builder job. This in my opinion is very useful to those who enjoys building, and they can earn money from it. Of course the payment will be based on how much blocks you've placed in a certain time like other jobs. This would be a very fun job for towny as I'm sure there will be people who enjoy building as a job.
Every job has a way to lose money too, like when you're a Digger, you lose money by placing dirt. Now if you're "Builder" made money by placing blocks, wouldn't they lose money by mining them?
