`  == Pipes and pipe tricks ==  DtG: You've changed several of my links by dropping the pipe trick and the uppercase initial letters in the titles of the linked articles. I agree with that form, I would have preferred to do it that way originally, and I did so earlier in my time at the Wikipedia. However, several other users have ``edited`` some of my simple links by capitalizing the initial letters. After a number of such instances I reluctantly started using the pipe trick to get a lowercase initial letter when required in runniing text. I've unsuccessfully searched for a written reference in the Wikipedia ``rulebook``. Where can I find a discussion of that point? I prefer your way, and I'll do it that way in the future, but I'd like also to be ready with an answer the next time when another user changes one or more such links. Thanks. Doc –   .`
