User blog comment:Top Agent PGG jr./Issue with use of templates and contractions in sentences/@comment-4189499-20140702100125

Contractions should be fine, as all but the most formal forms of English use them. While this wiki doesn't want to sound informal, it also doesn't want to seem overly stuff and strictly formal either.

On links, I think I agree with you. The general rule used across most wikis I've seen is that the first instance of a thing is linked, and then the next time it is mentioned, it isn't, unless it's under a different subheading. So, for example, to pull something out of the air, "Level 6 is a jelly level. In jelly levels, the objective is to destroy all the jellies within the moves limit". Level 6 is linked the first time, and so is jelly level, but the second time jelly levels are mentioned, it's not linked. However, it them mentions jelly, which is separate from the idea of jelly levels, so is also linked.
