The message also says than any contributors with a minimum of 15 on their account should send them their RIB details by email (ie bank account transfer details). Which makes me slightly wonder whether this might be some sort of scam.
ETA - probably not .. reading it again it says via their site mail rather than email. Or post. And I guess there is little anyone could do with just bank account numbers. I'm tuned to be freaked by emails asking for bank details
