Very welcome and regarding:
I think that my problem is that many of the terms in the drop down menus would be familiar to someone with publishing experience, but for the rest of us, it is as good as being written in Greek.
Both are feature rich, and sometimes it just a matter of playing around with settings to figure out what functions do etc. There are lots of guides to both of them online such as youtube views with how to's.... so if your looking to do something similar to MS Word but arent finding it, you can either find it by playing around or perhaps a youtube video showing how to carry out whatever your trying to do in the document. There are also books on each the the "For dummies" guides on them if you want a book to refer to.
They are about as close as you can get to MS Word without going with MS Word. Certain features so close to MS Word and the ability to save documents in MS Word formats, and open MS Word documents with these... I was surprised hasnt turned into a major legality issue between the projects and Microsoft with infringement. However to avoid infringement they may have left out that one feature that you require in order to be just that much more different to avoid lawsuits.
