I registered in an English program named 'iknow!' the other day not to forget English or to brush up my English.
I knew this site in an article of this blog.
Mekkan san seems to have been enjoying this program very much and I was also interested in it.
I'm going to enjoy studying English little by little every day.
Thank you very much for introducing this site mekkan san !
By the way, I've been learning English using 'hungry for words' too.
It's also very useful.
They are both free.
