Rotizelunch was easy to use once I figured out how it worked! It's great because you can invite your friends without having them sign up first which makes things easier when they're not available at work all day. The only thing about this program (which isn't really something bad) would be if everyone who uses their own personal email address has access through one account like we do in our office - but since most offices have multiple accounts set up then there shouldn't necessarily need to worry too much about security issues. We've been able to keep track of invites sent via text messages so no worries around forgetting someone's birthday anymore either :). Just make sure those invited are okay before sending as some don’t want others knowing what time/day etc.,they'll come into town!!
