In the UK we use Lego singular and plural - which although is still not technically correct - is better than "Legos" (Chrome even knows the correct rule as I type this).

Please America, take the "s" of Lego and put it back on "math" where it belongs.

BTW - looks like it is you that needs a a proof reader - I know separate is a difficult word to spell - but it is usually the second vowel which is the issue not the first or lack of it!
