Hi Gal
i have done this experiment to show the "new conversation" button
it seems the google groups programmers are using very big and wide screen
my experiment are using FireFox browser on windows XP with a 640x480 resolution
1- click (once) on the horizontal 3 lines on the top left group page. we will see nothing happened.
2- press the ctrl key and keep pressing while rotating the mouse wheel slowly toward you until the page split to 3 panes one for the messages titles, one for the authors and on the left the buttons (the ctrl with '-" keys works also the same)
keep rotating the wheel until the letters size becomes too small and barely you can see it,
now if you click on the 3 lines button the "new conversation" button appears under it. click on it and the messages editor appears. now you can make the letters bigger either by ctrl with mouse wheel or by pressing ctrl with '+' keys together
this absurdity happens when the technology companies getting rid of half of its workers
