Forums / Auto Correction

Both here and GOG I notice that a lot of what I type appears to be auto-corrected after submitting the post but the auto correction isn't grammatically accurate.

For instance:

"I used the machine to calculate the algorithm"

becomes

"I used the machine to calculation the algorithm"

For awhile I thought it was just because I was sort of senile but this happens far too often.

Anyone else getting this? Anyone proof reading their posts after submitting?

Other instance's seem to drop off words to counter what I'm really trying to say:

"Please don't go and shoot yourself"

"Please go and shoot yourself"

No but it's funny as hell
