"What's the best way forward"

If I were depending on this I'd write a patch and raise a ticket, linking any other issues the patch addresses.

"I haven't figured out yet how to get the e-mail address for a bug"

"A bit like perlmonks.org , where the "Title" box above is just too short."

It scrolls when you type.
