In my exploration of your site the only upload I have seen is post related. Am I guessing correct that if I want to share code with the community that I should do this via GitHub and post the link?
Or you can attach the code to a post or if it is under 9000 characters you can just post it just like you posted that text. There are
[code][/code] tags to make it look nice and not get trashed by the forum software.
There is a "How to use this forum" thread at the top of every board that would be good to read. It goes over most all of these sorts of questions.
I've already got 13 classes so a cut and paste won't work here. I did do a search but didn't find the response I was looking. So I think I'll take your advice and go old school and just read what is available.
GitHub isn't the only option but it's a good one. The biggest advantage of GitHub is that it makes it very easy for others to contribute bug fixes or enhancements to your open source project.
