If you LIKE it then give it the rating it deserves. If you LOVE it let those who wrote it know you appreciate their creativity. And give them THANKS if you found it something helpful and needed of praise. It's one thing to say you enjoy someone else's work...it's another to show it. Remember to rate your fellow Rpers, it means a lot. Thanks.
I would like my sig to say all of this but look better. It must be legible though, too crazy of font and some people won't be able to read the message. I personally think it is something most members should do for their fellow Rpers. So if it's flashy and one can read it, I think it'll be perfect to get this message a cross to those who read it.
