In October 2011 the Jamboree program activities volunteer began writing a monthly blog featuring a different Jamboree activity each month, starting with whitewater rafting on the New River. Each month's Jamblog is supported with an emblem, which will be available the month prior to the posting month. There will be a new Jamblog emblem released every month until Jamboree 2013!

Each emblem in the series features a design based on that month's Jamblog activity theme - the new emblem, for August 2012, highlights Brownsea Island! Each is a domed-tent shape including the Jamboree web address and measuring 2.5" × 3".
