Rupa -

Howler filled a big hole that we've been promised is going to be filled
for the last two years, but said filling is still not available.  That's
a significant risk and contribution on their part.

And the request is as to whether others have experienced similar
problems, which strikes me as completely reasonable on a users mailing
list.  If you can't help Edward, then I'd suggest you keep quiet.
