No problem... all here to learn.
On the bottom left of your wallet are some pictographs. The second from the right is a cloud. park your pointer over it and a little info frame will pop up, telling you your weight, total weight of the pool, and the expected number of days for your coins to mature.
Since I'm new to pos as well, I'm checking that frame several times a day. In relation to my own question here above, it seems now that after receiving a stake, the counter (for lack of a better word) is reset, resulting in a ridiculously long maturation time. However, in the course of an hour or so, it dwindled from 123 to 81 days. So I guess, it'll end up again at around 5-6 days. I've got invested about the same amount as you, you see...
Cheers,
