Guys I've hear you, it is clear that making it open source is the thing to do. I am not on github to develop this and truth is I never read the license.
[...]
I release it under the same license as Moneypot:
http://www.gnu.org/licenses/agpl-3.0.htmlYou don't get to make it open source. It was already open source when you got it, and you can't "un-open source" it.
You also don't get to choose how to license it. The existing license tells you that your fork is under the same license as the original.
Incidentally, it's well worth learning how to use some kind of source control. git is a good one to use, and github is a decent place to host your git repository. Having to upload the whole thing to mega each time you make any change to the site will get tiresome very quickly. git allows you to upload just the changes, automatically, and keep the same URL.
