Concrit

A portmanteau of the words 'constructive criticism'. Concrit is, basically, a useful review, one that makes helpful comments about plot, characterisation, or technicalities such as punctuation or spelling. It is one of the three basic forms of review, the other two being flames and worship. Flames can either be hurtful or amusing depending on the receiving author's mindset, and while worship is nice to get, it's not very helpful.

Concrit is also the name of a building material used in HQ.
