The company which hosts the dedicated server on which common-lisp.net is run is not offering such a service anymore, and the server itself is old and out of date. Because of this, we must migrate a lot to a new service.
There is also the matter of the future itself, what we offer and what we can do to help the lisp community. I was planning on having a bit more thought on this matter before asking others, but since this has come up, I figure that now is a good time to ask for input as well.
If you happen to be able to Donate some time, skills or funds, it would really help move things along. If you happen to IRC, #common-lisp.net on freenode is the place. Otherwise, comments and email will be read and dealt with promptly.
