Forum:MediaWiki date question...

I just logged on to Wikia and noticed Sarah's recent post. She said she had been in to wikis for a while now. I was curious to see when she had started out here. I looked up next to her username and it said "1,045 edits since 13. Oktober 2009". How did she get it so it said '13. Oktober 2009'? I presume she had the help of MediaWiki but how did she do it? -- Will k  (talk &middot; contrib) 06:52, August 31, 2010 (UTC)
