Can I use my Microsoft Office macros?
Even though the OpenOffice.org macros are written in a form of StarBASIC, it isn't the same as what Microsoft uses. Macros written for MS Word or Excel for instance cannot be executed via OpenOffice.org; you'll need to re-write them. This has its benefits - it makes OOo documents less virus prone.
