I had the following conversation with someone a few months ago, discovering that a simple word like "online" can mean different thing to different people.
Me: I am asking this on behalf of someone who would like to sign up for a class. You mentioned that I can sign up online. But I don't seem to be able to do it.
A: You can sign up the class online - just go to our website
Me: But I have checked the website, there is no facility for me to sign up online.
A: Yes, you can do it online. Try again.
Me: But I have just checked it again - your website doesn't have that option.
A: Yes, we do. Aiyah - you don't know how to do it online ah. Let me explain. First, go online to our website. Download the form which is in PDF into your computer. Then you print out the form and fill it the details. After that, you fax the form to me. So simple.
