Re: Problems with study material
From the Ubuntu Forums Code of Coduct (Which you agreed to in order to post here) ...
Section II - Posting Tips, When asking for technical support, part 7:
While we are happy to serve as a resource for hints and for asking questions when you get stuck and need a little help, the Ubuntu Forums is not a homework service. Please do not post your homework assignments expecting someone else to do it for you. Any such threads will be taken offline and warnings or infractions may be issued.
Ubuntu 15.04 Mate, Mint 17.1; MS Win 8.1, Win10 TP.
Will not respond to PM requests for support -- use the forums.
