Although editing others work it's one advantage of the wiki, it's also a big draw back. I well understand that it can be very soul destroying to have work you've spent ages on, changed. It tends to discourage ownership of the page. That's why I asked the question and put this in the site guidelines ...

Editors are free to make minor changes to any page such as corrections to spelling and grammar or adjusting page layout. However, as a courtesy to other contributors, you are requested to contact the contributor to discuss and agree any major changes in content. Major changes should preferably be made by the original contributor.

Really didn't mean to offend or upset, just wanted to keep a consistency going. Happy to leave be if you'd prefer.
Similarly happy for you to rearrange the text if you wish. You could copy it from "edit" mode in the GL page and alter in word or note pad, then just paste back to your page.
