[General] Simple information text.

Hello!

I'm about to start a new business in the UK. I already took a few English lessons to be able to communicate with my clients but as English is not my native language I just don't... feel it. I need to inform my clients about something, here's the text:

Thank you.

I wonder how many speakers of Polish there are in the Cayman Islands.
