Today/Tomorrow September 26 is SystemSettings and KCMs bug triaging day.
As described by Jeremy in this post in the KDE Gardening mailing list the purpose is:
1. Triage all bugs in the systemsettings product (and maybe the kcm product too).
2. If a bug is reproducible still, comment on it and find someone that knows how to fix it and convince them to do so.
3. Find maintainers for as many of the kcms as we can.
This is something anyone with a relatively new Plasma installed can help with so join us on September 26 at the #kde-devel IRC channel!
Personally I'll be on from 10am Spanish time until around 4pm with some lunch time in between.
