autorefreshing nndraft:drafts after postponing message

[Jesse Alama]

Hello,

When I postpone a message using C-c C-k in a message buffer, the
message is saved in my nndraft:drafts group.  When I am returned to
the group buffer, the number of messages stored in nndraft:drafts is
not updated.  How can I configure Gnus to automatically update the
number of messages in the drafts group, in other words, so that when I
save a message as a draft and return to the group buffer, the message
count in nndraf:drafts is updated, and that when I visit that group my
just-composed message can be edited?

Thanks,



Jesse
