A new punctuation mark needs to be created that could serve certain purposes.
A good example would be getting out of useless forum topics that have been diverted beyond recall by supposed contributors who actually want to destroy any meaningful thread.
I propose some symbol that looks like a small pretzel with an arrow pointing to the right, mid centre for a small distance.
It could equally point to the left for those who write Arabic, or either up or down in more esoteric texts.
The main feature of the symbol would be its ability to say something like –
I’ve finished saying what I need to say/ goodbye and sod anyone who comments afterwards.

I have already spoken with and come to agreement with Murdoch and Gates and have lodged patent application # X (deleted for confidentiality purposes)

In a few months time I have reasonable expectation that I’ll be able to depart any forum destroyed by fools without losing face merely by making use of my own squiggle.
Such a shame that I cannot use it now without giving away the secret.

You know, following your lead, I had a thought that maybe my next forum moniker should be A NON GAY, since I respect gay people. But then I thought, no, maybe people might get the wrong idea.

I had the wrong idea about you for sure, Mr Drama Llama.

You NON FARMER have started several threads complaining about other posters.
You have taken part in a few more, same thought, only you get it right.
Have you looked at you own posts? try that look at each of them once again.
Old age can be a reason for entrenched grumpyness.
Some times it helps to smile.
If its not age maybe its worth looking into.

Poor bugger's a gingerbeer, Belly, which means he KNOWS he's right, he doesn't have to guess...

Makes me wonder why some are here, if only to complain and harp, what's the point? Perhaps a better mark would be a pair of brackets, containing a large pair of letters...an F and an O !
