I went in and edited the heck out of it. I may, uh, have gone a bit too far. Please feel free to back out any or all of my edits, your picture is on the post but it's now fairly heavily written in my voice. Apologies if they're called for!
Rats rats rats. I think the invite link is pinned to that post, so I just scraped the text of your/our post and slapped it on top of the existing (other) welcome message. I should create yet another new person to test this, but ... I'm not going to do that just exactly right now.
