More of my favorite links

• The only TV show I actually try to follow is Babylon 5: sci-fi with a good deal of intelligence and a (gasp!) storyline.
• I have two PCs: a Dell and a Gateway 2000 and I have been mostly pleased with both.
• Still trying to figure out what Alanis says in "Uninvited"? Check the International Lyrics Server.
• Info about movies? Check the Internet Movie Database and you should find almost anything you want.
• I often consult MapBlast for maps and driving directions.
• The Rec.Sport.Soccer Statistics Foundation. Almost any soccer league can be found there, even the Brazilian Third Division and Regional Leagues!
• The rocking tune that is (hopefully) playing now comes from a really cute game called Gubble, by Actual Entertainment.
