Here's a barnstar for constant participation in VfD's (i.e. the Joder dicdef, my idea, ha ha) and in RfA's. You are an outstanding Wikipedian. D. J. Bracey (talk) 07:34, 8 August 2005 (UTC)

I...present you with this Cool as a cucumber award for staying cool in discussion of a recent incident in which you were involved. moink 14:04, 21 September 2005 (UTC)

I, Redwolf24, award you this Public Domain astronaut for your work with Copyvios. --Redwolf24 (talk) 05:22, 25 September 2005 (UTC)

I tried for quite a while to write a citation that would do you justice. But it was always too long for the page. I award you this simplest of barnstars for the simplest of reasons. You're the best goddamn admin I know. encephalon 23:22, 13 October 2005 (UTC)

Quis custodiet ipsos custodes? For courageous defence of process against admin abuse (and because a hard-hat might come in useful) I Doc (?) make this award (24/10/05).

I, Xoloz, award this Working Man's Barnstar to Splash for his tireless defense of the spirit of consensus in many wiki-forums. Xoloz 11:07, 2 November 2005 (UTC)

For your actions on behalf of the wiki in the face of advancing Wikistress, a Barnstar of Diligence. -- nae'blis _(talk) 21:27, 31 January 2006 (UTC)

The Original Barnstar for fixing the utc template thing and speeding up current events in the process. Saved me the job of having to dig into nested template hell. GraemeL ^(talk) 16:26, 5 April 2006 (UTC)

For this great post [1] on the Administrators' noticeboard. Hbdragon88 03:11, 24 July 2006 (UTC)

For your constant, diligent, and thorough investigations of Spotteddogsdotorg sockpuppets despite criticsm, I award you a Barnstar of Diligence. --CFIF ☎ 01:15, 4 September 2006 (UTC)

The Barnstar of Diligence, for thinking before typing, resulting in excellent comments at WT:RFA. James086^{Talk | Email} 23:47, 24 June 2007 (UTC)
