I'm working in a announcement block to display the last 3 announcemnts in the sidebar with a block. I have it working but it's only displayed in the admin sections, like configuration.
The code is based on the 'developed by' plugin adding the getContents to pass the announcemnts data to block.tpl.
Anyone can help me? any indication will be welcome!
thanks a lot!
