well .....I dunno.

You attempt to answer a detailed question about something complicated like Brexit, or how to set up a Fender amp.

And you simply don't remember to copy, or to put it into word. And then twenty minutes of detailed writing go up in a puff of smoke. And frankly much as I love Mudcat - life is a very short affair, and you think...sod it!

Been there...I bet most of us have at some point.
