Texpert

Correct spelling of phrase created by 82ASK to denote the researchers on their service. Highjacked and incorrectly spelt "textpert" by poorer text-message question answering services.

"AQA are so much better than 82ASK!"
"No they aren't - they make stuff up, charge you even if they can't answer and on top of everything they can't even spell 'Texpert' properly!"
