Issue tracking (bugs, feature requests) is a bit fragmented between the main website tracker:

* http://github.com/jywarren/plots/issues

and those of the "apps":

* http://github.com/jywarren/mapknitter/issues
* http://github.com/jywarren/spectral-workbench/issues
* http://github.com/jywarren/mapmill/issues

However, to make things even easier, if you are unsure how to submit an issue/bug/feature request, please simply fill out this form, which will be sent to the web working group. They will file it and email you the URL so you can participate/follow along.
