Just to add my 2 cents worth, (free speech and all)
My spelling sucks too, but a lot of the time its just typo's because i type to quick - too much enthusiasm to get it onto the page. Ist that what this forum is about - Enthusiasm?

if you can shred on the comp keyboard like you can on the guitar good for you, if you cant then it dont matter, and if you cant spell for toffee then well your playings still proberbly gonna be better than mine. I guess it depends what makes an individual happy or not.

like i said, just my 2c worth.
