I know this may seem like a shameless plug, but I can imagine it would help conversations in the on-topic area to have a tag to link directly to an article on the Infosphere. This is considering there already is a WikiPEELia tag, which I am not against, but this tag (that I speak of) may be used more often.
From a technical perspective, it is pretty much of a form of syntactical sugar for the already existing url-tag.
Examples:
"[infosphere]Space Pilot 3000[/infosphere]".
Would produce:
"
Space Pilot 3000".
With the url-tag:
[url=http://theinfosphere.org/Space_Pilot_3000]Space Pilot 3000[/url].
Should you want to link to something else than you intend to write, an optional argument could be provided.
[infosphere=Space Pilot 3000]The first episode[/infosphere].
Would produce:
The first episode.
With the url-tag:
[url=http://theinfosphere.org/Space_Pilot_3000]The first episode[/url].
It is possible that the name of the "[infosphere]" could be shorten to "[is]" or "[wiki]".
