I kind of thought you might like firefox. Everyone I've "converted" has. There's a reason it's got 10% of the market after only a year of official release. And now back to our program...
Hmm...
http://marymoongirl.proboards70.com/When I go there, I have no trouble getting to the site. I suspect you have a larger issue going on with your computer.
Is this your computer? I ask because some people are very protective of their hardware. I would not want my children doing what I am about to suggest - not because it can mess up the computer, but because I always like to do this kind of stuff myself. If it's your machine, go ahead and do this. If not, you may want to pass this advice on to the machine's owner:
Three things come to mind immediately when I see a site not resolving. You said you "scanned" your machine, but didn't say what for. I'll include both of these below, then.
1. Malware/Adware/Spyware. Try downloading and installing adaware to see if you have spyware/malware on your computer. It's a good program to have around anyway and doesn't noticably slow down any system I've installed it on. I always recommend a program named "Ad-Aware SE Personal" that you can download here:

3. Bad DNS. Something looks to be mucking with your DNS and that's not usually a good sign. You may have to manually add marymoongirl.proboards70.com to your hosts file (it maps to 67.15.146.40 as near as I can tell).
If you don't understand/can't do/need more info about anything here, just let us know, ok?
