Sweat Brazing?

I just had to log in, once again. It was much better before they bought out Supernews. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |

Wonder what is wrong? That is the first time in years. Who knows? Corporate customers, like Earthlink users aren't allowed to ask Giganews what is going on. Trying to reach anyone who knows anything at Earthlink is fairly useless. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |
