Don't let other people stop you from making mods that you want to make. Make whatever mods you want and experiment with whatever functions and codes you want. Release whatever you want to! There should be no secrets, that just holds everybody back. Unless there is good reason for the secret, as I explained earlier someone who found it may not want you to use it until his mod has been finished which is alright. However if his mod takes forever, then it isn't right to keep hiding it. Also if you found the code, use it! It's yours because you found it. If someone else discovered it and told you about it before you found it then listen to what they have to say about it, if they want to release a mod with it before it is used publicly then let them. You can still use it in your mods, but just don't share the secret about it until he says it is okay. If you found it though, you are free. Don't let anyone restrict you from making your mods, the only reason you shouldn't be allowed to release a mod is if it is stolen or a code was stolen/used without the proper credit/permission.
