Spelling on Habré

I did not understand how to fasten my post to “Habrahabr - Ideas for a site”, but that's not the point.

I propose to add the ability to check spelling in Habrahabr.
Since Lebedev has a “Orthograph,” it means that this is quite realistic.
Similar function is at documents and tables of Google.

Still I propose to make a normal interface for the design of the text, a la Word.
Also saw on many sites and it was more convenient and faster than manually editing tags.
