4. He answers and ignores us.
He haven't ignored you (and even if he did, what the matter), he answered to the message that was the most pertinent in regard of what he had to say.
I gave him a practical solution, he tried it and it failed. The only thing he had to say at this time was, "your solution don't works", and he said it.
5b. Inquirer answers you "just" per PM.
And he had a perfectly good reason. He did it for a matter of respect.
He is just a lambda person, using computer things but not knowing much on the subject, like 90% of the world. Therefore, he wasn't sure if the problem was due to his misunderstanding, or from the game. From his point of view, publicly naming the game and all, was equivalent to potentially incriminate someone, while in fact it was it's own personal fault.
And yes, it's part of what he said in the PM (just more directly, obviously).
5c. You edit your own post and hold every information also back so nobody else can learn anything from it.
Because it wasn't at all an issue related to unren, nor to unrpyc, but something that was misunderstood. If there were anything relevant in what happened in PM, I would have added it in my edit.
Seriously, why would have I took the time to edit my message, if it was to hold something relevant ?
