I recommend you taking part in the community a bit more by commenting on existing threads, whether it's a conversation about current affairs, or reading the work of others and telling them if you liked it and why.
Don't pass on what you get from English at Work as your contribution. It's someone elses work and it's unlikely to be relevant to most people here.
I would imaging your question hasn't be answered by other members because they don't know who you are, or perhaps didn't understand it.
As Bagit suggests, get to know your fellow members by taking part in threads with them. You can even direct them to your question once you get a rapport going.
Remember we're a community for writers, not a reference library.
