Hi!  I started mining with EMC a couple of weeks ago, and love it.  It's definitely the best pool I've tried in terms of performance, stability, and administrator enthusiasm  -- great job!

Speaking of donations, do you have an idea of what sort of donation level you'd need to cover at least the "hard" costs of the pool (i.e. easily quantifiable things such as hosting costs, versus time spend on the pool)?  Was wondering from the perspective of making sure I set up a reasonable donation level.
