Hi najmelliw!
In answer to your question, Lovatts is the name of a publishing company which issues a number of crossword and other puzzles in various magazines. Prizes are offered for some of the puzzles, which range from the very simple to the sometimes very difficult. (As you might have noticed there are "Stinkers" and "Demons" as well as "Goliathons" and "Monster Crosses". They are very popular, and although based in Australia, are also sold in New Zealand, UK, Ireland and some other countries. It appears they will soon be surfacing in the USA as well.
There are quite a few of us "Lovatts fanatics" who have made a home at A2K. If we have a difficulty with any of the puzzles, we are always keen to help each other out. We also very much appreciate the assistance and input we receive from people like yourself, who are not familiar with the books.
The best thing is that we learn and expand our knowledge and appreciation of the language - and exercise those little grey cells (as Hercule Poirot was wont to say).
And we get to make some good friends - so hop in anytime with your comments.
