But then again, most of the code is not tied to a particular maintainer anyway. For now, I guess the only way to know these things is to follow xemacs-beta. BTW, Mr. Johnston is not overly active at the moment, but William Perry <wmperry(a)aventail.com&gt; has also worked with the code (in fact, he's the initial author) so he is as likely to help.
