Mark, don't worry about "incomprehensible" expressions used by The Trader. He is doing it on purpose, knowing very well that even some other native English speakers and non-native speakers of English, despite being quite proficient in English, can't really get the meaning. Must be some regional-based English or whatever that nobody else cares about. Maybe, kerb crawler isn't slang or regional, but a technical term in IT. But who the hell should really care as he is someone who obvouslöy can't tell the difference between advice (noun) and advise (verb) and spell it accordingly? It's his way to mock about anyone else better educated than him in a lame and fruitless attenpt to compensate his inferiority complex about the fact he hasn't got a degree.....LOOOL

Not many western teachers or just westerners will not know what 'kerb crawlers' are , Turnoi. You have really shown us just how little English you know, and you should not comment on English at all. Will you apologise for your awful mistake? Before you depart for good that is.
