Hello Tintinabulation Wells, I hope you don't mind if I call you TW? If you think you've registered a pod but can't remember the log in details there's a line of text you can press under the boxes you fill in ("click here if you have forgotten your login details"). This will bring up a "podcard" which you fill in to send a temporary password to your email address. You use the temporary password to log in, then you can change it to something you can remember and order labels, fill in the number of bags you've made, say something about yourself / your pod.
Don't worry about asking questions, answering them is what we stick around for. That and talking about morsbags.
