Fedora beta questions

[Jared]

I don't remember who it was on the list but they said they are running the
Fedora beta. A couple of questions. First if i download .iso immages, burn
them, can i just keep using up to date to update all my software instead of
redownloading iso immages? Second, is Nepernicus configured and ready to go?
I saw it in the package list but heard it was also included unconfigured in
slackware. Third is emacspeak ready to go? Once again I had it in my red hat
9, but not ready to run. How stable is Fedora right now? Finally, if my
computer has a 10 gig drive for linux, 256 megs of ram, and 1 ghz processor
will it support Fedora? I know this computer ran red hat 9. appreciate any
info.
