### where to report bugs found using systems used by sage?

I am finding lots of bugs in systems used by sageMath. So not sure if I should report them to sagebug tracking as I have been doing, or to the other systems. The problem I can't find a place to report them for the other systems.

For example

>sage

I searched and searched, and can't find even a forum for Giac or a place to report a bug. is giac even supported system? I went to https://www-fourier.ujf-grenoble.fr/~parisse/giac.html and I see no place to report bugs. I clicked on the forum link there, but it is dead link.

Same for Maxima. I can't find where to report bugs found it is when using sagemath.

I once send email once about a maxima problem to maxima-bugs@lists.sourceforge.net but never heared back and I do not see it posted on anywhere on sourceforge.

May be sagemath should have an OFFICIAL web page, listing the exact location of where to report bugs found in systems used by sagemath if there are not to be reported to sagemath bug database?
