I'd like to ask about how to change the registration information.
Here is the place to ask about the grammar. However I don't know where can I send the question.
If I want to change the e-mail address, password or whatever, how can I change it. And also if I want to ask about the question like this, what e-mail address should I send it?( I don't know how to find it on this home page.)
I hope I can get the imformation.
