The first code I included was for market searches.
We could make this the BB code
Code:
http://chart.apis.google.com/chart?cht=qr&chs=350x350&chl={param}
This would allow users to create links.
And we can also make it so that new posts have an option to include the package name (i.e. link to market). That way developers just add their package name in their post so we can instantly find them in the market.
