The best advice i can give is to read read read. Get a book, read the web, it's all there, I've been on a year now, and i'll never ever go back , linux runs my server, not my desktops as i play many of the later games. And the support is'nt quite there yet. But for adsl, sharing, ftp, webserving, file sharing, all the important stuff, linux CANNOT be topped. My machines been on 6 months now, no crashes, no dumps. WOW. It was tough yes, but so satisfying. And the logfiles and monitors are a dream. Try doing that with a M$ box without Ģ1000 of extra software.
Keep trucking dood, well worth the payoff at the end of it
