Hehe, can of worms... I did write that TheLighterDark should feel free to stick with it if he wanted. I never intended to demand that he should stop or that he did not have the right to do it. Us oldtimers would never do such a thing. Simply wanted to point out what I deem to be unnecessary pixel pollution and a slightly awkward and futile way to express one's fierce individualism... but let's not argue this point any more, that would be off-topic.
To actively select him in my settings just to be able to ignore his signature seems a bit of too much work - also, if he did change his signature to "K11 is a grumpy old fart", I would not notice it. So, you crazy young'uns, I'm very sorry I was born... too long ago.
You could probably have the settings amended in your profile in quicker time than it took you to write the above post, lol. Wouldn't really call it too much work. But then like you say, if he changed it to something else, you wouldn't notice. Therein lies the rub.
