Is it edge or ubuntu-touch? I guess it should be the first one, but it has no description and also was used before for screen edges.
There is already the tag ubuntu-edge - I assume that would be the best to use ;)
It looks like edge is being used far more generally than it probably should - out of the three questions that appear, one is for screen edges, one is for a Thinkpad Edge (computer model) and one is for a Sapphire Edge (another computer model). The more specific one seems far better to me.
