Dear Lazyweb: 2nd bag at Ryanair

I'm taking a flight with Ryanair on Thursday and i happen to need to carry more than 15Kg the first bag allows you to carry. I know for sure that other companies (e.g. Aer Lingus) do not increase your weight allowance when you book another bag, that is, with one bag you can carry 20Kg and if you pay to ship 2 bags you can still carry only 20Kg. I've been reading the Ryanair Terms and Conditions and they are totally unclear so I'd like to know if any of you has taken a flight with Ryanair lately (say less than 6 months) with two bags and it meant that you could carry 15Kg per bag (30Kg total) or just 15Kg total.
