I've had the invoice for the server today, and paid it. It's now ours!
Thank you to those who have helped towards the hosting. I really liked the one with the comment "This is for you to use as you see fit, for the server, or the hosting, but hopefully a portion of it to treat you to a pint.". Cheers!
The hosting billing will start from the end of the month - so anyone who wants to and hasn't already
set up a regular donation (£1/month would be great), now would be a good time to do it.
