For B. I noticed the default Welcome message (at the top of the registration form) was changed. I do not agree with all the changes in the proposed designed. I'll try to find a middle ground between the technical language that was used before and the ideas brought in the updated version. Unfortunately, saying `login in order to edit` is false on a lot of wikis: public wikis can let edit right for guest users and private wikis might not give edit right to any user. I think we should be careful not to give the user false expectations about this.

Note that we could update this message depending on the distribution of rights in the wiki, but IMO it would bring more issues than what it solves.
