Any chance you could support the grid seed units? I have never really got them working bitcoins but if you could somehow support them I would point them at the bitminter... I would even send you one of them.
Isn't gridseed very slow at mining bitcoins? Does it make sense to use them for that? I haven't looked at the gridseed myself.
On the BTC luck chart, does anyone know what's the time frame for a column? Can one access chart data from whatever point in time?
It's the last 500 blocks (NMC or BTC, total blocks, not 500 of each). There's no way to move backwards in time - that's still on my TODO list.
