April fools!.. didn't cross my mind, but that would put this one in the category 'black jokes' and only for a selected audience to appreciate.
For now I assume the message is true though.
You are right, I hadn't the urge to react as well, even assuming the message is true. What's the point? At first I was glad he was alright, immediately followed with being upset he wasn't willing to give a sign of life by himself. This despite the fact various people were worrying about him.
After that, I realized I had all that emotions for a virtual person I never met and decided to make a better distinction between real and virtual life from now on.
Back to business: as we don't know the plans of "Random Virtual Jonathan" (RVJ) regarding Kisslicer it leaves us at the same point as earlier about the development of KS, but without the worries regarding Real Jonathan.
For me, this forum is grown much bigger than expected. I assumed we were with 20 grumpy old men by now. It's nice it's now grown to a platform for discussing other developments regarding Cura, CubeX, Simplify3D and so on. For me it can stay a Refugee Camp for all that nice side-kicks.
To help others with specific Kisslicer problems is for me not a priority anymore, until RVJ makes himself clear again about his plans with Kisslicer. The first goal of this forum was to keep KS alive until he surfaces again. Now he did (I assume) it's his job again.
