using openoffice for the first time you will be prompted for your full name and a registration. however there's the possibility to register never, which i prefer.
whenever you reinstall openoffice, because of an minor update or even a change in use flags, you will be prompted again.
this behaviour bothers me. as openoffice installs several dot-directories in your home (one for each major-version) it's ok to ask again after upgrading to another major-version.
I guess you are talking about openoffice-bin and not openoffice, as the later never asks you about registration.
Besides that: openoffice-bin uses the upstream binaries and asking for registration is the way Sun wants it, there is no possibility at all for us to change this
ahh, thanks for that info!
