Sound Solution and the middle click on registration

Question

Hello world! - well, Arch forum, anyway.
I've installed Arch successfully - finally - and I'm looking forward to using it. I work with multimedia, and this will be my main focus on "getting things done".
I have a few items for feed back to the maintainers of the installation page - which in itself was quite help, however I had to do a reinstall after hitting the boot section of the instruction sheet because I was missing a 1 GB partition that wasn't clearly described at the partitioning section. I know it said that this partition could be anywhere within the first TB, which in my case was anywhere on my disk, but just to keep things tidy I wanted to put this at the beginning of the partion table to avoid having to dance around it later with zfs and what not.
This first time I attempted to install Arch was about a year and a half ago. I had to give it up because no mater how hard I tried - I just couldn't get sound to work on my system.
This time, I didn't create my users for the daily drive until I had a zfs partition up and running. While I was doing this, I was also testing the system - as root of course - and I was extremely happy with the performance and that sound and video worked straight out of the box. However, when I created my users, I couldn't get sound to work for them. I booted up as root and sound worked again - then I switched to a regular user and sound worked. Rebooting and logging directly into a user account - sound did not work. I'm running an E17 set-up, and the toggle check mark to unmute the speakers/sound card was not available. Only after activating the sound system as root was I able to control sound as user afterwards.
To solve this I removed "audio" from all of the users groups - now sound can be controlled flawlessly - well as far as the users can tell. This was obviously the source of my problems with my first attempt at installing ArchLinux.
Also when registering I was asked what was the outcome of:
date -u +%V$(uname)|sha256sum|sed 's/\W//g'
I highlighted the answer from the terminal I was running, and - being the UNIX geek I am - middle cliked the answer into the answer field. Unfortuntately, the answer was wrong. After several attempts -double checking my work all the way through - the answer was always wrong. But then I right clicked the long answer and pasted this into the field then the answer was accepted.
I beg your pardon for mixing a few elements into the post - but I hope this also helps new users to Arch.
So, now I'm here.
Pleased to meet you.

I think middle-click should have worked.
