Microsoft have just made the new MSDN Code Gallery live. This is a site for sharing sample code, and I've posted some of my example code from previous blog articles. So far I've posted the following 4 resources:
MSCRM: Automate Local Data Group creation
Microsoft CRM report of all files related to an account
MSCRM - web page hosting to extend client script
Writing reports to use in IFrames and from ISV.Config in Microsoft Dynamics CRM
For reference, if you want to search for CRM examples, there's an emerging tagging protocol to tag all CRM examples as both CRM and Dynamics, so you can search on either tag. I'm also tagging samples with reports as 'Reporting Services'
