So these recommendations were made and I just get shut down.

Pretty par for the course as far as mailing lists go. Incumbents invariably assume that a new name to the list couldn't possibly know more than they do. And woe betide you if you prove them wrong.

As likely as not you'll get banned for some unconnected irrelevance, like top posting or bottom posting or interleaving or not interleaving or quoting to little or too much or just cos its the third tuesday in the month.

And chances are if you stay quite and continue to monitor, someone will pick up your ideas a month or two from now, implement them as their idea and revel in the "glory".

The good news is that if you can live with that, and the ideas are any good, you'll often get what you wanted anyway.
