I don't know to what extent you care at this stage of the production, but for what it's worth:
1. Library, Terrain page: affect not effect (affect is the verb and effect is the noun)
2. Library, Movement page: affecting not effecting

1) EFFECT is correct

Effect is positive, an action that changes something

Affect is after the fact.

Example: The earthquake in Japan affected the stock market.


Effect example:
The raising of American income taxes will effect the economy.

Easy way to remember which word to use: After = affect

@Razz1, El_Condoro is correct. Affect is a verb, Effect is a noun. In your example, "The raising of American income taxes will effect the economy", is incorrect. It should be "will affect" since its being used as a verb. If you wanted to use it as a noun, then your example should read: "The raising of American income taxes will have effects on the economy".

Oh crap!!! I have it backwards...........

It's one of the most common errors made by users of English (I teach English to senior students) along with separate (where the mistake is seperate). I have a lot (2 words) of respect for those trying to learn the language - it's not easy! Cheers

Well I'm a old dog and after time we can not remember everything.
