I apologize that I have spammed on many persons and lists with e-mail titled ‘Atsushi Shimono wants to connect on LinkedIn’.
Last night, I did some mistakes when I made a new account on the web service. First, I have made a filtered lists from my whole contact list, but I used the original one. Second, I missed the (hidden) upload form to register or upload contact lists from local storage (default is the input box for web-mail services), and used the input box for invitation.
So, if you received such e-mail, please just ignore it. Of cource, you can use if you want. :)
