Hi @Judy_in_Kansas - for some people that works beautifully. However, the issues with doing it "globally" (meaning, trying to do it for all members using a script or other automated method - at least as I recall from a couple of months ago when @leah-ganoksin-admin and I discussed this) were these;
1) The "introduction" emails were done for some people who signed up in certain ways, at certain times - it wasn't consistent across the entire history of the forum.
2) Many, many people had two or three email addresses during their tenure as Orchid members. To the computer, those look like different members. Others joined, left, re-joined, changed names, etc.
One thing to keep in mind - we took 258,000 individual Orchid "posts" that were basically emails, and wrote a whole bunch of software to move them over into a threaded, searchable forum format. The idea was to try and make it look and work like the forum had been in existence this whole time. Of course, any time you try to take emails and turn them into something they weren't originally formatted to be, you have issues.
My hope is over time, most of that stuff will get corrected, old posts will be "revived" and brought current (which is already happening - that's really cool), etc.
Sorry for the digression - in any event, I do think it would be very, very cool to be able to see when people joined, especially because we have many hundreds of people (of the many thousands) who have literally been here for over 2 decades. Not a lot of internet forums can say that!
I'm adding this to my list of "cool stuff we need to figure out how to do in an intelligent way" -- @leah-ganoksin-admin and I will figure this out at some point. It's worth doing.
First up though - we are working on a re-design of all the content categories on Ganoksin.com and a whole bunch of categorization work, that is going to make everything easier to find.
