So you're taking control of the topic; right?
That's actually really good. I don't know why I hadn't thought of you earlier You could totally do it and well I'm always around [despite what people might think or SAY about me]
The grammatical mistakes REALLY bug me; it's not just about the mistakes that might occur in anyone's posts; it's the matter of not using what you don't know how to use; if you know what I mean! Using the stuff you've just learned might be useful though; but you know correcting every single post is just impossible! Especially if we're gonna get into talking about different subjects and stuff.
As a teacher, I seriously don't think this topic can be beneficial regarding to educational usage per se; but it can help people practice they already know and eventually make perfect.

I still think it's better to have separate topics for each of these subject matters; I mean hell we have topics for [no offence] but the most stupid games of all time! Why should we even hesitate when it comes to this one!

I guess we need to set a couple of rules for the forum we're gonna make though; I actually wanted this forum to be a place people could share ideas with non-Persian people and help develop the English VERSION of the site.

Seems like a big shot but it's doable.

P.S: You shan't practice The Dark Arts or even come close to that by this matter; until The Dark Masters decide to honor you so
