Its a nice idea shoby, and i suppose it would curb the spamming
you can just imagine it though really, the amount of abuse you would get if you were struggling to come up with a solution for something or it taking a while to solve, its a bit different from typing on the forum,
And yes it would provide a faster more efficient service if you like too, I have never really looked into this stuff much so i dont realy know, maybe someone here has already experienced this type of thing!?
some folk would be shy to actually communicate on that level too.
maybe i nice idea as a general chat type of thing?
