Users with the Highest Number of Contributions as of August 7, 2016
Unfortunately there is no way transfer contributions made as an unregistered user to a registered WikiAnswers account.
There isn't a 'best user' on wikianswers. There is only those who have lots of contributions.
Orange is a motif of WikiAnswers; this stems mainly from the Orange Guy, the WikiAnswers Community Mascot. However, depending on the primary contributions of a user, orange is not necessarily the most common color.
Of course! Becoming a user on WikiAnswers shows all your contributions and lets you volunteer for a supervisor position and other cool stuff.
Message Boards and Question Discussions both count as community contribution points on WikiAnswers.
WikiAnswers Supervisors and Community Assistants can see all contributions by an IP address.
Clearing your browser's cache and cookies will clear your history. Contributions made under your user name or IP address cannot be deleted.
Although opinions will vary, this distinction can easily be given to the original creator - Chris Whitten (user name: Chris). Without him, there might not be a WikiAnswers (and that would be a sad reality for us all).
If you are a registered user, you can go to your contributions page by clicking on "My contributions" on the blue sidebar. Then chose "filter by: Questions Asked" and you will see a list of all the questions that you have asked on WikiAnswers.
If you have logged-in to WikiAnswers with a user id and password you can look at 'My Contributions' in the 'My Pages' area. You will find this at the bottom of the blue area on the left hand side of most WikiAnswers pages.
Based on the actions of the user, Supervisors decide whether or not to block by looking at past and current contributions, and Supervisors also receive advise from the other Supervisors and their Mentors. If the Supervisor sees many reasons to block the user, the user is then blocked.
The recommended figure is not a percentage. And no, there is nothing to indicate 'comparison' with other contributors in the figure. It is a guide to how useful other users have found the contributions that the user has made. It can be misleading.
