Hi Stacey,
As a former Concentric user who switched to SBC a while back, I can vouch for
the good things that Andy had to say about the service. It was reliable and
widely available nationwide. However, it got to the point eventually where the
amount of spam that I received over there was absolutely absurd, just beyond
the ridiculous. I'd been using it for a while as a backup dialup account since
I already had DSL, but when it got to the point where I was receiving several
hundred messages a day, most of it spam, I said the hell with it and split. I
just couldn't take it any more and figured it wasn't worth spending an extra
$20 a month to wade through all the garbage.
