Comment 68 for bug 1504445

I copied all this information to Dmitry Torokhov and <email address hidden>.

Is it normal to not receive answer?
Will I ever know that my contribution has been read by someone?
I can understand that by habit and a taste for conservatism, they like their email system but it's kind of opaque system that forbid all feedback to contributors. We don't know if we are taken under consideration, if we have been useful, or if we did all wrong and we need to review out approach to contributing...

Sorry for disturbing here, because this message doesn't belong here. I had great help here, but if I write over there, I'm afraid that my email (from a modest contributor) will not even be open... So if someone here knows how to get my remarks to the right person, thank you to do so.
And if someone can answer this last question, I'll be happy
How can I make sure that my efforts were not just for me but that later Ubuntu will not bring that same bug to other users?
