Hi Bob
The plugin works for me on two blogs I run so I know it works. Below are the 5 reasons it would not:
1) Forum is actually not there
2) DNS isn’t updated
3) You pointed at an embedded page instead of the actual forum
4) Does PHP have cURL enabled? (just *having* curl isn’t enough, it needs to be in the copy of php actually running web requests)
5) Did you modify the template improperly? It’s possible that curl can’t process the pages.
