Considering Opening a Beta Program for any PH's who want to try. What are you thoughts?

Hello fellow PH members, I am looking for some guidance. I am considering starting a full open-access beta program for any and all PH members who would like to try out my new product before launch and provide any feedback and suggestions. The Beta would be hosted under a single account so there would be no need to sign in just press a button giving users full access. The only limitation I would be putting in place would be a 100,000-word count limit to allow as many users as possible to be able to use the product as easily as possible. I am looking for the following feedback, advice and/or suggestions: - What are your on this approach? - What would be the best way to communicate this to as many PH members as possible? - Can you provide any advice on the most effective to kick this off in the next 2-3 days?
