Been a while since I’ve given the mXX series a shot (developer, QA only releases). These will eventually become OOo 2.0.
Waded thru IssueZilla, submitted #24962 as an enhancement for the default installation directory; confirmed a few other new/unconfirmed bugs. We won’t have to use setup -net any longer, as the installer has become clever enough to ask you what kind of installation you want, and tell you if you don’t have administrator rights.
Excel as a database is a funny read (with the cartoons and all). On a more serious note, a well-structured spreadsheet does form the creation of a simple database (that’s how OOo gets it done, simply, without a back-end).
