Let me know about the mistakes please if any

[e2e4]

I can't get grammar in these sentences below.
The sentences are form a native English speakers forum board.

A:
It's so the can charge government depts extra for the "new language"
What does "so the can charge" suppose to mean?

Hiberno-English is quite different from what they speak over in England.

For a start , especially the start of words, we don't get mixed up with 'f' and 's' and don't drop 'h'

at the other end of the scale we have a lot more Nobel prizes for literature per capita than other English speaking countries

B:
There have only been three, and two of them ****ed off out of Ireland the first chance they got.
"was" or "had been" maybe?
C:
aren't you forgetting George Bernard Shaw ?

D:
No, I'm including him as he emigrated to London before he started writing. I'm 'forgetting' Seamus Heaney as he's from the UK.
No need for "had emigrated"?

Thanks

In A, 'the' is a typo for 'they'.

B and D are fine as they stand.
