Most of the phpBB projects available on phpBB Smith are created to be used by any phpBB users that desire the features they provide, free of charge. Many are also open source, allowing anyone to improve on them or redistribute them so long as the terms of the license are observed.
Developing and maintaining modifications can consume a great deal of time and effort. If you like some of these projects I have made and would like to show your appreciation, there are many ways to do so. One of the easiest is to add a link to phpBB Smith on your own site. If you would like to do this, feel free to use one of the images below. Please remember to save the image and place it on your own site, as hotlinking to images on this site has been blocked.
There are lots of other ways to show your support, also. Purchasing one of my books would help you learn more about phpBB. Bug testing new hacks, requesting features, and lending a hand to others in the phpBBHacks.com Support Forums would be great. Even just a friendly e-mail saying, "Hey, thanks for the great phpBB hacks," would be a gem.
Another option is making a donation via PayPal. Any amount is helpful.
