On mobile, there should be a pointer to the CC forum (coming up in the browser).
On PC, click on your CC's name to open their homepage.
Use the "Forum" tab (right marker) below the picture on top.
On the forum page (picture) use the "write new post" tab (left).
Reminder: CC forum software is different to the main forum. Each post is preset "send replys by mail". You have to unckeck it in the options tab.
JCKelsey: I took a screen shot, I guess I have to upload somewhere else??
Yep. See the "scorecard" post on top of the Community Help forum for advice.
