The project has two parts:
1. Mirroring pcpuzzle.com/forum. I found a very useful program called HTTrack, which allows automatic mirroring of websites. I am currently mirroring the forum with it, and hopefully it will generate some useful results. After all files have been downloaded, I will parse the data using Python and store them in database-happy format.
2. Recreating a proper Level Exchange website. I will be recreating a proper Level Exchange website, powered by PHP. All current comments and pictures will be uploaded to this website.
This New Wonderland Archive will provide features that this forum lack, including On-the-fly level archive download, Level-with-CustomData archive download, support for files larger than 800kb, and Level Series support. It will also feature just-for-fun features, such as Level Of The Month, Level Submission Statistics, and others.
Due to the vast complexity brought by the lack of the actual database data, this project will take several months to a year before completion. Most of the project time will be spent on unpacking data and data integrity check.
Before continuing with the project, I would like to collect opinions from members, who will be using this project the most: Do you think it's a good idea? If the community feedback is positive, then the development would begin. I will also look for help along the way, so stay tuned.
Thanks for reading, and have a good day.

(and before you ask, in this post, "Level" stands for both RTW levels and WA Adventures.)
