 https://manual.lubuntu.me/stable/B/Contributing.html?highlight=bug#support-and-bug-triage mentions "And we could always use help with art/graphic design!" and "Bug Triage" but gives no hint where such people may actually contribute.
 Is it some intentional filter to keep only truly dedicated?
 https://phab.lubuntu.me/w/bugs/ is the guide for reporting bugs, we should add it there.
 No filter intended.
 @matkoniecz for a phab account please email the Lubuntu council. The list info is on this page. We can manually add your email address. We use the tasks in phab to help shape the project but bugs go in Launchpad. Sometimes they get linked together but more often the tasks are a little more general than a standard bug.
