You ever seen that show on MTV pimp up my ride. Well got me thinking isnt key part of Umbraco pimping!! You need events calendar then get onto
codeproject and find a calendar hack it to make it work with Umbraco source data, expose some public properties and create the macro. Or say you want to extend what is available in the xslt editor you need some more powerful string manipulation get onto
coreweb download the library static the methods, drop the dll in the bin and add entry to extentions xml file and there you have it your Umbraco has been pimped.
