Safe Or Not?

How do you tell if a website is legit? Josh received an email from SCSU, (which I thought had a filter on the emails it sent out) about a website through which we found some info on doing typing work from home. Needing extra money, and the attraction of the flexibility of this type of job appeals to both of us, but it just makes us nervous with all of those people out there who may be running a scam...

Any suggestions?
