Unless they sign their message, no.

I usually sign them, but in case you were wondering, I gave you the one for the example project.

I think it would be nice if the username would be written somewhere.

Thanks Camatose

I've read in other threads that some people have had bad rep with messages like "I hate that guy". Maybe If their name would appear, there would be less reviews like that.

Sure, but would they be honest?

We cant guaranty anything. People are what they are.

what is the rep formula anyway, what makes up those little green squares? Just curious...

In fact, while I´m being curious, I still haven´t figured out what all the symbols are all over the page. I´ve found some in the faqs but all aren´t explained...

Is there an overall explanation somewhere??

I think it's important for the usernames to remain anonymous. They're supposed to be a more unbiased feature, and I think anonymity is important to community building without childish slander.

Basically, when someone gives you positive feedback, your reputation is increased. When someone gives you negative feedback, your reputation is decreased. The amount that your rep is increased/decreased is based on the amount of reputation-altering power that the person who rated your post has. Reputation-altering power is a combination of your postcount, your own rep, and whether you're a DaniWeb staff member.
