@giantbear nagged me for a year, but I was sceptical at first and only joined in July of this year. I do not know now why I did not join earlier, but in my mind with my teaching I thought I will never have time to post on steemit. I would like to be more involved but I do what I can and it is a welcome relieve from just teaching. O and do not feel alone about not understanding the internal workings, I still have no idea what is going on. I post and read and comment - that is about all I understand LOL
