I was following Sherry's kind advices in my sandbox at enwp http://en.wikipedia.org/wiki/User:Elitre_(WMF)/Sandbox:
<<you can create an {{Infobox person}}, with parameters like "name" and "occupation". Within those parameters, you can type the wikicode for any templates you want. For example, you can give it a name parameter of "Alice Expert((citation needed|date=July 2013}}", which later gets processed properly as a template. >>
An infobox appeared (well, a box with my sandbox title, actually), I saved, "your edit was saved" message appeared, the box isn't in the page anymore.
Tried again, same thing. No trace of my activity in the history. Win 7, Vector, both Chrome and FF.
Thanks,
E.
