Check your spam folder...
It appears that a couple of webmail services - hotmail.com in particular - are quietly filtering emails from the discotd5.com domain to spam.
Donors will always get a "Thank you for your donation email" from the site within a few minutes of the donation being made, and I try to get donor accounts setup same day, but it can take up to 2-3 days if I'm away, and have limited internet access.
When the account is created an email advise the account has been setup is sent. This contains a one-time login link.
If you have donated and didn't get a "Thank you email", first thing is to check your spam folder.
If 3+ days have passed, and you haven't got an account creation email, first thing to do is check your spam folder.
In particular if you have used a Hotmail account to donate - just check your spam folder for email from @discotd5.com.
