This is to all the anonymous users and even some of the registered users who contribute to the wiki:
Whenever you make an edit to an article, it gives you a text box to put a description of your edit in. Please use it. It is so, SO much easier for me and everyone else to make sure that nothing is being vandalized if there is even a phrase describing what was changed.
Now, I'm not saying that the edits being made are totally incorrect or invalid, but it is simply more polite to leave a description of what you changed, even just the title of the sub-section that you altered, than to just make an edit, leave the summary box blank, then move on. It takes little-to-no effort to write words in a box, so please, just SOMEthing is better than nothing.
