Mailing lists are a very inefficient means of communicating on an open-source project.
I've setup forums for RoundCube at my website. I am *more* than willing to let these be permanent for the project.
Link to the forums is here:
http://forums.thetechgurus.net/index.php?c=5
There are 3 forums as of now: Discussion, Coding, and Bugs.
I would like the developers of this project to contact me also so that we can further discuss intergrating the forums into the main project webpage.
