I've gotten a few emails and such from people telling me that submitting skins is broken. Something about it chopping off half the code or something. Unfortunately, I am unable to recreate this problem -- and there are still many skins added every day that work fine.
That's not to say that there isn't a problem -- there clearly is. I'm just having trouble seeing it. So if you've had this problem, can you please post a comment here? Please include what web browser you are using as well as your operating system. Hopefully that will help me narrow it down.
Update: If you're having this problem, please let me know in the comments whether or not you're using <textarea> tags in your skin or not. Thanks.
