More kudos for Duolingo
I spend a few minutes each session with Duolingo lurking in the Spanish Discussion section. Occasionally I try to answer someone's question, but - more often than not - I've found good answers and/or clarification for issues I've wondered about but not queried. The Discussion section can be an excellent learning tool. Thank-you all who contribute to the discussions. And, once again, thank-you, Duolingo.
