Hi Joffm,
I agree with 2. I don't know if 1. is that necessary. I mean I do it usually, but as long as the way someone asks is educated, I am fine with it. We do not need to spend too much time on formalities.
What annoys me the most are those that expect to receive an answer immediately, and if this doesn't happen they "report" the post to the moderator or send private messages. I think the response time in the LS forum is often sensational. If you need to wait a little bit longer, so be it. But I compared to other forums that I frequent, the LS forum is either excellent or doesn't have to hide. Other forums where I received excellent support are Openmediavault, pbxinaflash and lately Shotcut.
But so far, I am amazed by the help and patience (e.g. Tpartner and also you Joffm). I sometimes am inclined to write something evil, but then rather skip the question...
