I have had many discussions on this particular topic with various people, and we've finally reached the decision that WoW Watcher will be a completely open-source project in the same manner as is Wikipedia, where it will be possible for you to download and install a complete copy of the source code and user-contributed data and setup your very own clone of WoW Watcher, modify is as you please, and even redistribute your own copies of the website (as long as they remain under the GPL)
We've taken this stance as we have always believed in the openness and principles of the open-source software movement and want to assure you, our supporters that we will never sell out to gold farmers, and that when you contribute your hard-work to this project, you will *always* have access to the work that you have contributed.
I think that community is clever enough to keep collecting data into one repository together and I cheer to your decision for GPL and not LGPL or other license. Thanks a lot for all you do for us!
