Drupal 8 needs as much prodding along as it can get to make the anticipated late summer launch in 2013.
With the launch in mind the next worldwide sprint weekend is coming up just after the London DrupalCamp weekend - on the 9th & 10th of March. Yes Mothering Sunday is also on the 10th in the UK so make sure you don't forget those ladies in your life inbetween git pushing code.
The global Drupal event calendar Drupical is doing a nice job of keeping a record of the sprint events coming up over the next few months.
If you're new to the idea of collaboratively code sprinting then you'd be well looked after over at the Drupal Ladder project site which aims to get 1% of the huge Drupal community contributing to Drupal core by 2014.
If you're involved with a user group and have some time on March the 9th and 10th to organise your own contribution to the global sprint then you should jump over to the Issue Sprint Guide for a quick read and then get it promoted on Drupal Groups UK as soon as possible.
If you don't live near a publicised sprint venue then fear not - you can still contribute to Drupal 8 issues through the Drupal Office Hours initiative which does a superb job of categorising problems for different types and levels of user wanting to get involved - you don't need to be a developer!
