[olug] RAS for dial-up ISP question

[Charles Bird]

Damn, Damn, and damn...thats what i kinda thought.   
If i could offer a resonable rate for people then I'd get 
the t-1s. I'd have to charge DSL prices just to pay for 
the lines.  
I'd like to charge 12.50 for basic super low profit 
dial-up and use any extra for funding for the non-profit 
org. and do some good to the poor.
