[SoC] Re: [GRASS-dev] SoC proposal

[Margherita Di Leo]

I would like to thank everyone of you for the answer.
I have to say that this project is not just my idea but it is the effect of
the discussion I had with Jarek on how the GUI shall work. We know that the
project is challenging and eventually the help of all of you is more than
appreciate, especially on the wxpython side.
I really hope to be worthy of your trust.

Thank you very much
