Your girlfriend's out of town and you're looking to have the guys over for a boys' night: cheap beers, football, some kind of debauchery. But you can't stand the phone, text messages are for sissies, and "reply all" e-mail chains just clog up everybody's inbox. What to do? Send a Manvite (www.manvite.com). Launched last month, the free online invitation service is designed with men in mind: choose from events such as "Drink Beer," "Watch Football," "Vegas Trip," and "Cougar Hunting," and check off the "Hotties Allowed" setting if you're willing to let a few choice females into your mix. The e-mail invitations come with all the standard features - customized message, response tracking, and comment posting - but none of the cheerful balloons and perky martinis that adorn its more feminine brethren. There's also a post-game wrap-up page and the option for guests to accept or reject your invite based solely on its masculinity.
