Le Ministre de l’au-delà was someone I went to art school with. We were good friends for a couple years but had lost track of each other. As it happened he told a story on the Board that sounded familiar and I checked with him, and it was him.
Kind of…
I once opened a thread posted by Oy! asking for a bit of Portuguese translation help:
Can anyone translate English into Portugese?
She was asking for help translating a short note to accompany a gift for her housekeeper. When I saw the woman’s name (“Nair”, pronounced nyEER), and location (Trenton), I figured that the odds were pretty slim of having two Brazilian women with that name cleaning houses in Trenton – she is good family friend!
I asked Nair about her friend (Oy!) and she had nothing but kind words to say about her. One of these days we still need to all get together for a Brazilian churrasco (bar-b-cue).
That was cool.
I found out another Doper lived in the same apartment complex as me.
I used to work at the same place AeroDave works, but in a different building. I never did knowingly meet him.
FairyChatMom and I were at Purdue University at the same time, but she was a senior and I was frosh, so we didn’t meet. Oddly enough, I’ll soon be moving to the same county where she now lives, and she likes the idea. I think she needs to have her head examined. 
Mahna Manha and I were best friends in high school. We lost touch for ten years, and then she joined the MMP, and we were chatting, and I had this Twilight Zone feeling, and I asked her if she was [insert real name] and said I was [insert real name].
And she was and I was and I just went to a Christmas party at her house yesterday. 
It was weird. All of cyberspace, a board with thousands of members, and we reconnect.
