there may be little positive feedback, I guess. So I created an account for the forum to leave a big THANK YOU!

The first version I used must have been something like StarOffice 4.3, the first I owned was SO 5.2, and then I shifted to OpenOffice(.org) when it introduced the XML file formats. So I am a convinced and longterm user since then and hardly ever regretted my decision.
OpenOffice gave me the possibility to mostly do what I wanted to (with writer, base, excel, impress and draw - in that historic order) in an efficient way, and the only thing I don't like is, that it tends towards imitating MS Office although it was better in many ways. I understand that it is crucial to get as many users as possible, so I acknowledge the decisions towards MS Office.
What I like most is the long term usability and stability, and I do not only keep my office files from more than 10 years ago, I also use and re-use them. And if one crashed, I nearly always could recover them by opening the zip bundle.
By that, I enjoyed the progress in LibreOffice, but didn't really need it. Although I switched to LibreOffice on some machines, I am always glad that there is OpenOffice, too. In my eyes, it is the more stable and efficient branch of the project. This year it was my fallback tool and salvation in a book project that I started with LO Writer;

So if you get the software maintained, I will probably continue to use OpenOffice for another 20 years. And I won't switch to DTP software (Scribus) for the next book project neither as I regularly do for magazines, brochures etc.
OpenOffice is a great, great software, even if it didn't evolve much in the last years! (maybe even: because..)

Keep patience and persistance!

A very satisfied and content user
