He first joined the site in April 2011. Prior to joining, he read Wikipedia in his free time and even followed some discussions on site, occasionally weighing in as a IP user. Calidum is a WikiGnome, meaning his main contributions are to fighting vandalism and minor copy-editing. He is also a participant in move requests and is known to make non-admin closures to less contentious discussions.
Since joining Wikipedia, Calidum has authored two articles. He wrote Charles II de Cossé, Duke of Brissac on July 17, 2011 and George Godsey on September 20, 2011. The latter would go on to appear on the Main Page's "Did You Know" section four days after being written.
Later in 2011, He decided to run for arbitrator; it didn't end so well. In the election Calidum (Hot Stop at the time) ended up dead last with only 12.47% support, one of the lowest totals in years. He decided to not run in subsequent elections (at least not yet), instead opting to endorse candidates publicly in 2012 and 2013.
For those interested in such things, Calidum made his 500th edit in September 2011, his 1,000th edit in December of that year, his 2,000th edit in August 2012, edit number 3,000 in December 2012, his 4,000th edit in July 2013, his 5,000th edit in March 2014, edit number 6000 that June, and his 7,000th edit that October. Calidum is also among the top 10,000 Wikipedians with the most edits.
