Read about the origins of NotifyBot in this blog post.
NotifyBot is offered as a free community service -- so long as it doesn't place excessive load on my Mastodon host (pdx.social) or my VPS instance.
The bot is open source, published here: codeberg.org/crosenthal/mastodon-notifier-service
The author of this bot is Courtney Rosenthal. You can contact her by email at cr@crosenthal.com or on Mastodon at @courtney@pdx.social.
I welcome your feedback and questions.
