When I have many tabs open in my browser then I cannot easily distinguish Slicer wiki and Slicer discourse tabs:
(the last two are Slicer discourse and Slicer wiki - they look the same)
Could we slightly change the site icon so that they show up a bit differently?
For example, add a small discourse icon in the corner: 
I’ve made the small adjustment by modifying settings here. The old and new favicons are available on the site assets page.
Checking using either chrome or firefox, the new favicon is not displayed. I think it is because an .ico file need to be uploaded instead of .png
I tried using an *.ico file without success. Also after reading the hint in the setting, I found A favicon for your site, see http://en.wikipedia.org/wiki/Favicon, to work correctly over a CDN it must be a png
Worth noting that Wikipedia indicates such icon files can be 16×16, 32×32, 48×48, or 64×64 pixels in size
In the settings page it is written:
A favicon for your site, see Favicon - Wikipedia, to work correctly over a CDN it must be a png
Some browsers cache the favicon for a while. I would give it a few days/try clearing all browser caches to see if the icon gets updated then.
After uploading a 64x64 / *.png version of the icon, it now shows as expected.
