Hi @Heather105 and @Matt6,
I understand that you are trying to contact each other to arrange sharing a car ride, but I've had to removed your personal details for your security, as this is a public forum. The best way to contact each other privately is to hover over the other person's profile picture and you should see the option to 'send a message'.
Please let me know if you have any questions about this!
Kirstie
