Hi!
The main page shows a thread named "aperiodic sampling" (http://www.hydrogenaudio.org/forums/index.php?showtopic=66679) by cjanscen. But this is not accessible nor appears in the subforum where it's supposed to be in (Scientific Discussion). Might this be a problem with the slash ('/') in the topic's description? (just guessing)
Cheers,
SG
Known forum bug. Thanks for reporting anyway.
