If you have something that requires a lot of explanation, and/or you would like it reviewed, and/or you would like it to be easily pulled into a user’s editor with a somewhat automated process of creating a workflow and setting credentials where they are needed, and/or you want to be able to monetize the use of the template, then you should go through the creator program and publish a template.
If, however, you just have a workflow example that you’d like to share, it might be way simpler to just post it in the Tips & Tricks Category right here in the forums, like the one I did for pagination, for example.
