DP:CAPS

Mediawiki is case sensitive, except for the first letter of the first word, which is autocapitalized during article creation. This ended up being problematic in cases where other parts of a multiword title were capitalized. Current policy is not to capitalize words in links / titles unless they're an abbreviation, the first character in the string, or a proper noun. If there is some confusion, try to leave a redirect.

Good:

[[Model planes]]

[[Cyberdyne T-1000]]

[[Fly Fly Hobby]]

Bad:

[[Model Planes]]  (delete and fix)
[[Grand wing systems]] (delete and fix)
[[multiplex easy star]] (delete and fix)
