cheers!

i recently joined suprnova's zec-pool and was wondering what the donation each user can select is used for.
looked around the site and couldn't find any info on this.

a donation based pool is an interesting idea albeit i doubt enough would be willing to donate to make up for a low/zero percentage of fee's but since there is a fair 1% fee on suprnova (with occasional 0% special's) i wonder out of pure interest what the additional donation would be used for.

anyway, thanks for the good work and support!
