1778 be sent to the Gnus Bug Exterminators.
1780 At the bottom of the buffer you'll see lots of variable settings.
1781 Please do not delete those. They will tell the Bug People what your
1782 environment is, so that it will be easier to locate the bugs.
1784 If you have found a bug that makes Emacs go \"beep\", set
1785 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
1786 and include the backtrace in your bug report.
1788 Please describe the bug in annoying, painstaking detail.
