so, I just started and put about 10 MH/s for more than an hour on ipominer pool
it seems to mine WC, but all balances stay at 0 (also unconfirmed), the round shares do seem to increase
ipominer pool is 2 GH/s versus net 32 GH/s for WC
does this just mean that for last hour ipominer did not find a block ?

UPDATE: balances have been updated :-) the concept is really nice, I am looking forward to the actual returns :-)
