I noticed a question which popped up in Active tab few minutes ago, and was tagged with micromax-unite
Looking at all the questions in that tag, I see that most of them are related to the device "Micromax Unite 2 A106" with one exception of "Micromax Unite 3 Q372".
I think a tag wiki is definitely needed now to signify the purpose this tag serves, preferably intended to serve a series of devices under a common brand.
I don't know anything about this device, or I could have tried suggesting the wiki.
