About [[Wikia:Awc-metrics-articles/en]]

Should be Content pages or just pages to avoid Wikipedia-centrism.

Same for Awc-metrics-article-avg-size ("Avg. art.<br />size").

In the works.

Actually, I don't think this one is a good idea. I do agree that this is Wikipedia-centrism, or rather -- Wikia-centrism, as we use the same terminology for stats.

And since this is probably only ever going to be used at Wikia, where the term is fixed and used all-over, changing this for added neutrality would be a bit of an overkill, IMHO.

Sounds sane. Feel free to use different - preferably consistent - terminology in your translations, though.
