is this free software good?what about compatibility issues with MS office versions.anyone who has used it
Yes preety good. WordArt fonts are not accurate though, but for normal editing stuff, it absolutely a fine replacement to MS Office.
One of the best alternative for MS Office. I am using 2014 Beta. No issues so far.
LibreOffice blows it out of water
Libre office is good. They just need a decent interface. I hate living in 1998 to make docs and presentations. At least they should allow add ons like Firefox.
