Hey, guys ... you might recognize me from the #!Crunchbang, Debian or LinuxMint Forums.
I have been a Linux user, for almost 10 years - now. Started my Linux Journey with Fedora, way back when. Moved to 'buntu for about 2 days, then found LinuxMint. A short while later discovered Crunchbang (Ubuntu-based). Now, I only use Debian. (or Debian-based Distros) I have played with Archlinux, Manjaro, Sabayon and Slackware - from time-to-time.
I used the Xfce DE, almost, since my 1st day with Linux.
Now, I am a Dev/Tester for Xfce-4.12
I primarily use either Openbox or Fluxbox WMs.
I am a Admin/Moderator for a couple of Forums - LinuxMint Forum, LostintheBox (Fluxbox) Forum and Ask.Debian.net
Also, I am a Debian-Maintainer (DM) for the Fluxbox WM package.

When Jessie/Testing goes into the 'freeze' - I will switch my sources.list to reflect the Sid repros, just to play around.
I am discovering that I rather like Debian-Sid (unstable). After Jessie/Testing becomes stable, I might just keep this install of Sid and have another partition with a 'stable+backports' Debian on it (for work).
I just downloaded and installed the 'last' ISO for SparkyLinux-Xfce-3.4.1 -- going to play around a bit. Looks promising.
I really, like what you've done with Debian-Testing -- my kudos to the SparkyLinux Dev and Testers.
