AdeyC: Yes, I did that, I made a backup of all the data and I don't want anyone adding anything at the moment. The thing about MTF players being on the TF site was a mistake, it's fixed now.
Once the domain is transferred, it will not work right away, but you'll be able to access the site in read-only mode at MTF Tennis Tipping Statistics
until January 4th. Once I set everything up at the new site, you'll be able to add tournaments again. It will still be the old site, though, just a cheaper hosting.
supertom: The idea about importing the results is interesting. Not an Excel, but a CSV file. I'll have to think about it.
