We've all been there. You desperately want to tell someone something (like their cubicle has a horrible stench coming from it) but you don't want to hurt their feelings. Sure you could slip a note under their cubicle, or pay off someone to do the deed for you, but why go to all that trouble when you can use a website called NiceCritic.
When I saw this site on Lifehacker, it reminded of StopForwarding.us, the website that will send an anonymous message on your behalf to tell a certain someone to stop sending you forward emails. Except with NiceCritic, you can choose from a variety of categories, including "Neighborly Suggestion" and "Personal Hygiene," then go ahead and add the recipient's name and email and it'll go directly to their inbox.
