When I click your link, firefox gives me a warning for a non-secure connection.

The rules state that " You must be the author of the Source-Code." but the only posted example is taken from Daniel Shiffman's Nature of Code book. It's the SmartRockets example from chapter 9, found here. Except the proper credits at the top of the sketch were removed.

It only facilitates posting of code, which can be done in many places already (some of which are actually able to run the code online). Often used sites to share code are OpenProcessing.org and GitHub.

So, why have you made it an HTTPS site, instead of a simple HTTP one? I know it is a trend (this forum, GitHub...) but I am not sure it is always necessary.
