There's a thread on BBC BASIC. One user posted an answer. I wanted to ask a question about this, and tried to use the @name tag to ping them.
Most of the time when I do this a little tag pops up with the user's name. This time that did not happen. When I posted it, it does not appear it parsed it at all.
I thought it might be because they posted the answer, but then noticed that it worked fine in other places when replying to the OP.
I've seen this before in other parts of the SE system, does anyone know what's going on?
