We've decided that scripting and coding releases on the forum must include all required source code for them. This has now been added to the forum standard rules
(module releases have already had this rule since the release of 0.1).
Main reason for releasing the source code is security - If we allow releases without source code then anyone could release a compiled malicious script/module. A release with only a compiled module/script doesn't really help the community either, since you can't learn anything new from the code, nor can you modify it for your personal needs.
Thank you for your attention
