Can I claim a SlideShare username taken by someone else?
Pranav Bhatnagar November 12, 2010
Unless an account is impersonating you, you cannot claim a username that has already been taken.
If the username you want is already taken by an active user, you can always add numbers, underscores, or abbreviations to the username to get one that works for your on SlideShare.
Please note that if you use company or business name, logo, or other trademark-protected materials in a manner that may mislead or confuse others with regard to its brand or business affiliation, it may be considered a trademark policy violation. If you are a legitimate trademark holder and someone is misleading users, please get in touch with SlideShare support and we will look into this on a case by case basis.
