Trying to get more visitors so posted to a few of the sites that @johndatserakis suggested recently: https://www.indiehackers.com/product/rsvp-keeper/i-just-posted-rsvp-keeper-to-a-bunch-of-sites--Lo8_0y3yYGvCRmcX2sB
Paid to support some of them and for express review. Let me know if anyone has recommendations of other sites to post to.
