A couple more questions:

I was always taught that it is improper to format sentences as follows: Even so, it appears several times on the Wiki. As far as I know, the correct version of the above sentence (even if it's a poor/improper example) should be: The justification for this is that the ", and" is being used to join two separate thoughts. The two thoughts need to be complete sentences on their own if ", and" is removed. What are the opinions on this, and does the difference between British and American English have anything to do with this?
 * "The man ate ice cream, and went back for seconds."
 * "The man ate ice cream, and he went back for seconds."

Another potential error I keep noticing that may or may not be because of the differences in English involves semi-colons; people are using them to join a complete thought with an incomplete thought, like so: The correct version of the example above (as far as I know) should be:
 * "They were able to activate the effect again; the shock of the effect reconnecting the TARDIS to some part of its interior."
 * "They were able to activate the effect again; the shock of it reconnected the TARDIS exterior to its interior."

Is it ok for me to correct these errors when I see them, or is there a specific reason (such as British English or a Wiki-wide decision) why they are present? I apologize if my questions seem stupid; I'm not used to editing a British Wiki, let alone one that is so large.
