Keep the nominations coming!
And to answer a few questions:
Yes, you can nominate more than one person, but only one will be selected each month.
No, a larger post count doesn't mean a person is more likely to be selected. Any active member is eligible.
Yes, you can send separate pm messages, to nominate people. Just make sure to put "MOTM Nomination" as the title of your pm.
Cheers,
