As part of the IBM.com family... developerWorks shares the common "IBM ID" that all IBM external websites use. When we first launched My developerWorks, our Edit Profile function would only allow a member to view their IBM ID credentials and other IBM profile elements.
We heard from many of our members the desire to update and maintain all their profile elements in a single place. As a result, we have just delivered an enhancement to Edit Profile.. and now allow the full edit of all of your profile elements from your My dW profile.
I have also heard much feedback on offering the ability for our members to change their screen name, expect this feature to be delivered in the next few months. Finally, our user testing (and my own experience) pointed out the awkwardness of registering at My dW.
We have a new registration process in the works... and I also expect this feature to be delivered in the next few months. I really appreciate feedback from our membership.. my goal is continuous improvement of our user experience on My dW, so please keep your comments coming!
