Is it possible to send from myetherwallet to the daohub?
Yes. But I'd advise sending from the Mist wallet as its from there you can watch the smart contract and vote on proposals. Daohub explains all.
Actually, tho' this is prolly because of my underpowered Windoze rig, I had a huge hassle sending my ETH from Mist - so much so that I wound up using geth (which went through with no complication.)
