Good catch! I just tried to find contact info for the pool owner, to have him warned, but no luck

. I guess there is no point of mining with that pool after the fork unless pool gets upgraded to 1.1.

Sorry how are you able to check it is the older version?
At the top of the wallet click Help and then click About ROIcoin Core
The very top line will give you the info you ask about such as this from my wallet:
ROIcoin Core version v1.1.0.000 (64-bit)
