The Plone Community is coming together in one of its largest global sprints ever in honor of the 60th Plone Tune-Up - which is scheduled to take place on Friday, September 21st. Ten worldwide organizations have pledged a record total of close to 30 programers, testers, designers and marketers to advance the open source content management system.Plone Tune-Ups are regularly-scheduled, one-day mini-sprints where members of the Plone Community from around the world come together online to grab some outstanding tickets from the Plone Trac system and help move Plone forward.Tune-Ups offer an excellent environment for new developers to get started with Plone development and understand the process used by the community for identifying, tracking, and resolving issues with Plone. Development experts from the community are available online during these events to provide help and answer questions. Tune-Ups also offer structured time where established developers can spend a couple of hours picking out and resolving important tickets. Tickets for each Tune-Up are tagged as to level of difficulty and relative time needed to resolve them, making choosing the right tickets to work on a straightforward process.The Tune-Up format and events were the brainchild of Plone development and hosting company Six Feet Up, and September 21st marks the 60th Tune-Up since the first event was held in 2009. Tune-Ups have been responsible for closing close to 400 tickets since that time.You can find out more about Plone Tune-Ups by visiting the Plone Tune-Up Network, which will provide all the information you need to get started with this important work.Whether you are a long time Plone developer, or just someone interested in getting started, you are invited to attend the 60th Plone Tuneup on Friday, September 21st, 2012.
