Testing

New discussion button - a discussion should be posted in the proper category. Before it was created in 'Code Questions' always, except of Design challenges.

Announcements - no changes, created in 'Code Questions' for all tracks, except of Design.

Please test with 5+ discussions in Code Questions/Code Documents. By default 5 recent discussions from each category are displayed. You should see the More discussions link. Please let me know if you want to change the styles.

All announcements are displayed in a separate section (MarvelApp: https://marvelapp.com/prototype/c06bg41/screen/77911803),
not duplicated in Code Question / Code Documents / Discussions sections in a group page.
