[Pgfplots-features] Is it not possible to open new issues in pgfplots' sourceforge place?

[Ignasi <ni...@gm...>]

Hi all,

today I wanted to open a new issue about this bug(?)

http://tex.stackexchange.com/questions/207450/fillbetween-from-pgfplots-does-not-work-inside-groupplots

in http://pgfplots.sourceforge.net/ but I couldn't. In fact the still 
open issues are from 2013 so I suspect it's not possible.
Is it? Is there any other place to do it? I'd prefer not to use 
Christian's email address.
