From last Friday, I had busy days. So I completely forgot to join this IE3 blog. But my friends talked about the blog in our line group, then I remember that I didn't accept invitation! Firstly, I failed to join so I was getting panic. But I remembered Dr. Armstrong's word"Don't panic", and I asked my friends for help. Soon, my friends replied me. Then I could solve the problem and eventually I achieved joining blog! I appreciate dear my friends! Thank you :)
