Okay, I've been seeing a few pages in Wiki that created in the User namespace that were not supposed to be done that way. In order to help, I would like to document how to access your userpage for a creation or modification.
First step, you need to make sure that you are using the right editor to create your Wiki page.
To do so, click on 'Settings' - 'General Settings' - Scroll down to 'Miscellaneous Options' and select 'Standard Editor - Extra formatting controls'
Save changes and you are done
To access your Wiki page, there's an easy link that everyone should use.
First, click on 'ShaveWiki' in the menu bar.
Second, you will on top left corner your username as a link under the 'Home' button. Click on it and you are there.
The rest should be what you want the page to look like. Keep in mind that Wiki is part of B&B so make sure that you are following the Terms Of Usage.
If you have any issues please feel free to ask in this thread. If you rather not, please send me a PM.
