No, Eric, I didn't. Now I do, however, and comments work like a charm -- Must be some weird coincidence, huh? 😉
Seriously, I'm beginning to dig the whole concept more and more: of course the comment-functionality shouldn't be part of lars-blogger (or any other package) it would break the whole modular/generic approach of OpenACS that attracted me to it in the first place...
Thanks for your help,
Tom
