I really appreciate the support that has been offered from everyone, all around. And, I definitely think this is going to be needed in the future when we start feeling the load of having a huge 500k user community and have to upgrade *again*, then we can start taking donations.
And, just an an aside, most the upgrades you're seeing is a result of zIWT cranking up around the same time that I'm attempting to get a side business going. Thus the big fat pipe, etc... so, there's really no costs for zIWT specifically, as these are true business costs to me for attempting to get the hosting service up and running. It's just good timing for zIWT! :) As for personal expenses specific to zIWT (hardware upgrade), they're minimal (~$150 and spare hardware laying around); just consider them my donation to the community. :)
So, hang tight, I REALLY appreciate the offer of support and we'll definitely need it in the future, but hang on to it until then.
