It wasn't what I saw in his post, it's what he saw in my post at #7. He was asking me how I managed to reply to another poster, but addressed it to myself. I have no idea how that happened.
...how about the To: line in #13?
The poster (markos33) simply deleted the "post to" info from the address box and typed in a new To: at the top of his post. It only looks like it's addressed to me, but it's not in my pings.
...if you want to see something really weird take a look at post #6 1/2 in this thread.
Oh, I know the one you're talking about. That got my attention, too. I had to go back to it three or four times to figure out how he did it. Pretty darn cool, if you ask me.
I've tried that before and get an error message saying "no poster by that name." 'all' is the only thing I've ever put in a 'to' line that stays and isn't an actual FReep handle. Oh, well.
