@DanAdair in the customize plugin, you want to customize translations. There are a couple you might be interested in. First select the email namespace, then look for greeting_with_name and digest.title.<period>
You can then customize the wording.
I got a test NodeBB setup and I'm going to try the gallery plugin next. Except, I think I just determined that the lightbox gallery plugin is not a full gallery, with management to go along with it. Is that correct?
I was previously running on SMF with the Menalto Gallery. This gave me folders, user galleries, and admin functions for the gallery side. Anything like that for NodeBB?
