Added captcha to edit dialog
From OpenFOAMWiki
In the past few days a lot of spam-messages were added to the Wiki and had to be removed. To make things more difficult you will be asked a simple arithmetic question when editing/creating a page. Sorry for the inconvenience.
Should you experience any problems, please contact me
