hi, welcome both of you. (Ex-Noosa myself Cru)
Note that if you created a Pixelfed account it is a separate account to your Mastodon one.
Follow your Pixelfed account from your Mastodon one, and then when you post on Pixelfed boost it on your Mastodon.
Anyone can follow your Pixelfed account from their Mastodon one.
Hope this info helps!
