That's right, you read it right. BiD have gone free. Madness usually happens a little time after Christmas but it keeps getting earlier and earlier each year.
Basically this means all the themes you used to be able to get from BiD, where you had to pay for the pleasure are now free and you can download. They've also got loads of tutorials and are setting themselves up to become a Joomla resource worth bookmarking.
Bottom line, if you are after some training or would like to know how to create your own theme for Joomla this is a good place to start and get an understanding. To top it all off, you get free themes, which can't be bad, can it?
