Welcome to the forum, and I hope you like your car.
Certainly if you get involved in the forum a bit, people will appreciate the advice you give them, and will use your referral code. I’ve been using the forum over a year, but in that time I’ve had two Tesla referrals. Unfortunately one was cancelled earlier this year, but I think quite a few of us have experienced that because of the Covid upheaval.
And don’t forget you can also join Octopus Energy for cheap car charging, and once you’re with them you can give out your referral code to friends and family, as well as by direct message if someone asks on the forum. Join Octopus using a referral code and you earn £50 credit. Then you get another £50 if someone uses your code.
You can put referral codes on your profile page, but they’re not allowed in posts or signatures.
