I didn't know I could use this on my computer. I found it on my mobile phone and this is the first time I've actually sat at my computer and logged in. I really like using it here, but I absolutely love using it on my cell phone. This program is AWESOME and I even shared it with my Mother. I'm excited to see what language she chooses. I'm pretty sure she's going to share it with her brothers and sister too. This is very similar to Rosetta Stone, but I think it's much better!! Cheers Duolingo!!!
