I posted a link to my Haiti idea in the comments. Wasn't sure if it was seen.
I'm not sure on the mining, as to what time it'll start. I did see that buying is closed now. A friend tried to get in this morning and the option was gone.
Since they're ramping up very slowly, I wouldn't expect to see much over the next few days. Of course, we could be pleasantly surprised. :)
As for the allocation, are you in the right miner? Along the top you see some blue boxes. You must have the Zcash one selected in order to assign Zcash allocation. I don't know their formulas, so I just leave it at 100% Zcash. Right now there are no other options for Zcash mining anyway, though I'd expect that to change in the not-too-distant future.
