Client sends me support email concerning the CMS.

There's not enough details to go on, esp. browser info, so I ask her to fill out a support ticket.

She does, but doesn't enter any browser info, AND mistypes her email address so I have to correct it to reply to the right email.

I send her to whatbrowseramiusing.co and ask her to send the info to our support email address.
She emails support directly with these words: "I am using Google bowser".

I reply: click "Send to my designer" on whatbrowseramiusing.co and I give her exact steps to fill out the three form fields

She replies: "There is no 'Send to my designer', I only get the option to buy the domain."

I'm like "Whut?!" Did you mistype the URL? Why don't you click the link in the email? (Paraphrase)

This time I get an official email from whatbrowseramiusing.co, telling me that the client is using Safari 5.0.5. Which is five years old.

At that point I replied and said we really can't support this older browser, and included a link to the Firefox download page.
