To submit a code, fill out the information on your code as outlined in the instructions. For the actual code, ideally you should just enter a URL to the full working demo, to make it easy for others to check it out. However, if this isn't possible for you, you can also submit your code inline on the forums, by attaching it.
* For straightforward code, just attach it as a single .txt file * For code that consist of both code and images/other media, zip up all the files and attach it as a .zip file * Should you need it, this forum supports file attachments of the following type: .txt, .zip, .js, and images (.gif, .jpg, .png etc). * Again, if possible at all, it's best just to submit the URL to the script instead, for ease of review/ critique by others.
