For some people it can be difficult to tell a friend or roommate how much his breath smells or how plump her butt looks in those new black pants. Most know the difficulty of telling attractive members of the opposite sex how much you like them. At www.justatip.com, you can tell anyone anything in an anonymous fashion and not have to feel guilty or embarrassed.

Justatip.com allows you to compliment or criticize your friends or loved ones, and your name and e-mail address will not appear anywhere on the e-mail.

The site is split into the Compliment and Criticize categories. Under each of these categories are eight sub-categories such as Hygiene, Appearance, Fashion and Style, Habits and others. You can either give a compliment regarding one of these sub-categories or tear the person apart.

The most popular use of the site is the criticism e-mail. The site asks you to choose a problem, answer some questions about it and then they will "tell your friends so you don't have to."

You can easily and anonymously tell someone he is a sloppy drunk, a bad kisser, a jerk, a bad date or any of the other choice insults. You can also tell someone she is beautiful, a great dresser, a wonderful girlfriend or whatever ego-boosting compliment you choose.

So, when you've decided that you can no longer stand your roommate's funky body odor or you just have to tell that certain someone how gorgeous his eyes are, click on Justatip.com and send your comments without any worries.
