There is such a desperate need for technical writers that anyone and everyone is welcome. My only fond hope is that we deliver quality. The minimum requirements for technical writing are good English-language skills, and proper use of grammar and punctuation. Typically, in most of the user manuals that I have picked up in India, I have always found errors after browsing through a few pages. Some of these errors are gross and some of them are subtle.
