Although the journal claims to publish two issues per year, v. 1-v. 4 (2009-2012) appear to have been published in only one physical issue per year.
Volume 2, no. 1 & 2 (Mar. & Sept. 2010) is published as a single bound volume with continuous pagination, but with two internal title pages (designated no. 1 and no. 2) and individual articles designated no. 1 or no. 2.
Description based on: Vol. 1, no. 1 (September 2009); title from cover.
