Newly Formed LLC

Hello All,
I am newly formed LLC and I’ve filed my articles of organizations in New York State for Rockland County. I got a letter stating that I need to publish my business in the local papers. In New York that will run me at least $500. Has anyone formed an LLC in NY? If so did publish and if not were the consequences. To me it seems a little outdated being that you can go on the NY State website and look up any corporation. Any input is appreciated.

If you don’t follow all the rules for operating an LLC, then it will be ignored if anything happens and you will be personally liable for any LLC debts.

Can you publish it on Craigslist?
