bboard again ... It seems this package has got a bad reputation and for some reason "forum" is better. I always thought bboard was one of the core "standard" packages of ACS at all, and, having a high version number, would be fairly well developed. That was probably a wrong judgement ...
In your OpenACS 5 announcements I found that one of the plans is to give more information on the status of the different packages. That would be very good! In the present state, when you are new to OpenACS (like me), it is even hard to find out what a certain package is good for.
