No, it doesn’t send the tweet to twitter from a forum post. Let me test on another install as this one is a child theme and the test site is not.
Ok tested on test install now its not working at all on WP single 2.9.2 BP 1.2.1
I have test site in a folder though not sure if thats messing it up or not. On other site I have not upgraded BP still at 1.2
