I don't know if this has been mentioned before, but I just stumbled across GitHub "gists" (https://gist.github.com/). This allows you to post code samples, etc for others to look at or download, as far as I understand it so far. It seems like we could use this for library files or even for code samples in answers to questions.
Right :-) Have a look at the Forum Help guide: http://docs.textadventures.co.uk/forum/
Well there you go. :) I guess I should RTFD once in a while, especially when I've been away for a period of time.
