the forum digest is missing, this is a big mistake, most of the forums out there are inactive because users don't have the time to search for the topic they want to answer.
On the other hand, look at sackexchange and yahooanswers network, they are the most active Q&A sites out there, why? Because new questions are shown om the homepage so the users answer questions immediately.
People don't have the time to search every section of the site, i can't stress this point enough, this is why most forums die, on yahooanswers, you can't reply to the users who answered your question, because some users want to answer and leave, they don't like to reply back.
i asked a question on ubuntu forums today, and the answers i received are like this
hi
<answer here>
bye
they didn't reply back to me, having said what i wanted to say, the design looks pretty neat, but i wish we have the option to go back to the previous design from the options, or design our own theme, like on twitter, using javascript and html, that would be cool
