I have reverted this edit. Please look up the purpose of wikicode before removing it. You do not know what this does to the article if you do it blind. SpinningSpark 06:27, 30 July 2010 (UTC)
I have also reverted your edits to control system and control system (disambiguation). Please see MOS:CAP for the use of capital letters. The purpose of a disambiguation (dab) page is to quickly guide the reader to the correct page that they are looking for. Consequently, a dab page should have the minimum possible amount of text to make this task as simple as possible for the reader. Since there is already a control system article, a reader entering "control system" in the search box will go there first. The dab page is linked at the top of that article. If the reader then goes to the dab page it can be assumed that they were not looking for the control system article, so it is counter-productive to have paragraphs of text on this at the top of the article. Just a brief definition and a bolded link is the usual format. It is possible that some items on that page should be removed, but please do so in line with MOS:DAB, not because they do not logically belong together. SpinningSpark 06:57, 30 July 2010 (UTC)
