Just in case someone got confused by the latest common-lisp.net announcement.
ECL is not an orphaned project. ECL was hosted at common-lisp.net for some time, in a period in which Sourceforge experienced frequent outages. At some point it was more favorable for us to return to SF and so the common-lisp.net page was emptied and redirected. With the new change of servers the redirects stopped working. Besides this, for some reason I had forgotten to change the email address at common-lisp.net and I did not learn about this.
So, the summary is that ECL is still alive, even if the maintainer is going through a very busy phase that should finish some time around June.
