Forum:About 'Template talk:18 warning'

Is there a way to change this Template about minor warning / parental control so that it will only show up once (at the first visit) and/or otherwise only show to not registered visitors? Since I am not a minor it is hard to say what is wise or better, but for me it is quite annoying to see it all the time and especially since it also shows up on the printed version of a page. Apart from this, I consider a 'spoiler warning' far more important then this one.

An example of this template use is here: http://scratchpad.wikia.com/wiki/IllusionGames and the related pages. Locustus 18:32, June 12, 2010 (UTC)


 * You can hide any element from the printed version with class="noprint". For example, this text won't be printed . Use print preview in your browser to see the effect. --Ciencia Al Poder (talk) -WikiDex 18:25, June 12, 2010 (UTC)
 * You could add it to w:c:scratchpad:MediaWiki:Anonnotice. -- 18:43, June 12, 2010 (UTC)
