There is absolutely no reason for this manner of condescending tone and post to be made in public on a technical forum.
If you wish to provide these types of helpful advices and assistance then it is best handled privately by way of PM.
The purpose of communication is to communicate...if you know that "exspensive" was meant to convey the same meaning as the word "expensive" then the tenants of the intended communication were fulfilled.
Grammar nazi, spelling nazi, whatever the pet peeve and OCD, your venue for expressing it is through private messaging. Expressing your concerns/opinions on these topics openly and publicly in the technical forum is unacceptable.
Politely asking for clarification to a post is acceptable and expected. If grammar and/or spelling errors render the message unintelligible then it behooves the reader to request a more intelligible version be drafted and communicated.
Epic. There's no plural for advice though
Still, thanks for making me giggle IDC
