Could the date a volunteer registered on our Galaxy site be a metric that's added to their User Profile? I constantly check users' profiles for all kinds of information to make sure I'm communicating with them appropriately and building a relationship/volunteer experience in context of all the stuff on there - their location, age, skills, availability etc. Easily/quickly knowing when a volunteer registered on our site would be hugely helpful for this context. 

For example, if I found someone who was a perfect match for a certain role I needed, but also saw that they hadn't yet signed up for any opportunities, I'd want to know if they registered a month ago or two days ago. That would influence the way I reach out to them and what I would say. I know I can figure out when they registered on our site by clicking on their emails and checking the date of their welcome email, or by creating an email blast filter with "date added after," or there are other options involving exporting spreadsheets. But those are all frustratingly cumbersome ways to try and find that info.
