I run an old DotNetNuke 2.11 website that uses the NTForums module from Active Modules, Inc. NTForums is actually outdated and the current product has be rebranded as Active Forums. Active Forums supports DNN 3.1, 3.2, 3.3, 4.0, and 4.3. The only reason I haven't installed the upgrade yet is that I keep having trouble with the DNN upgrade itself (not the module upgrade). Last night I had some trouble with a sql injection (fun times!). Luckily, the injected script was basically harmless, just annoying....
