You may edit article pages in BoWiki with a view to improving the quality of the information.

At the top of each editable page there will be an edit tab, click on that and you will access the editor screen.

The editor screen shows the current document including the formatting. The document is not WYSIWYG, i.e bold text won't show as bold.

Formatting text is a mixture of using the editor buttons and using known code & character combinations.

When you have made your edits you should preview your changes and if everything is working save the page.
