Re: Use cases for web based signage.

Dear Gisung,

Thank you for your proposal.
Your proposal is really fruitful.
I'll read your proposal and try to import it to the document.
Give me some time.

BTW, there are some pictures in your proposal.
Can I use them for the document ?

Best regards,
Futomi
