Forgive me for jumping in with yet more unsolicited advice, but I can&#x27;t help thinking that all your users should be paying at least $5 per month.<p>An example transition plan:<p>* switch new users to a free trial -&gt; sign up to $5&#x2F;month for continued access
* observe conversion rate from trial users to paying customers
* perform `conversion rate x existing active user base` calculation
* send apologetic email to existing users pointing out that free != sustainable, with offer to grandfather in free access to any who feel strongly enough to send you a personal email about it
