On the new signup / new enterprise pages, the help links that go to the wikipedia need to open in a new window or tab.
This stops people being taken away from the signup pages and stops users data they have already filled in being erased.
So clicking this link will open (http://en.airlinesim.aero/wiki/index.php/Game_Rules#Naming_conventions_for_holdings_and_companies) on the same page and not in a new tab/window.
This causes any data you have typed in prior to clicking the link to be lost.
Trivial but it happened to me when signing up, might make people not be bothered to carry on etc
Thanks - I just added this to our task management system.
