As the title says, what is your all time favorite DNN module? I have several. I have worked many years with Ventrian News Articles but that is no longer developed. I replaced that now with Live Articles from Mandeep.
The other one is Evotiva-DNNSearchAndReplace from http://www.evotiva.com/Products/DNN-Search-And-Rep... That is really handy if you have a lot of HTML content in some modules and you need to change something.
