I have three suggestions, but these are nuts-and-bolts issues rather than recommendations for ways of keeping people on topic.
First, an email function (or PM) on the forum to directly contact forum members.
Second, I notice that I am signed-off the forum after a undetermined amount of time. I much prefer to remained logged in, can this be changed?
Third, in addition to an the RSS feed, it it possible to have a subscription function which emails when a topic is updated?
I hope I am not going off topic here, as I am rather liberally interpreting the meaning of ‘suggestions for improving the CDags site’ for my own purposes.
