JSesh is used and supported by the IFAO .
JSesh is featured on sun's swing sightings previews 23!
I have just downloaded LibreOffice 3.4.3 (one of the versions of OpenOffice). And I am very pleased.
At last, the hieroglyphs are antialiased.
Copy/Paste using RTF with EMF as graphical format works well, and allows to paste back the hieroglyphs into JSesh.
The only problem (If I insist on finding one) is that PDF copy/paste doesn't work yet.
If you are the editor of an Egyptological journal, I suggest you allow OpenOffice documents alongside with Microsoft Word for submission. The great thing with OpenOffice is that everyone can have the latest version, and its behaviour is quite the same on Mac and PCs. It has most useful features you could want (except grammatical correction) : text revisions, automated table of content, index... And it has actually a better support for some non european languages than some recent versions of Word!
p.s. Well, I found an annoying bug however : the version I'm using loses pictures when saving them to M/S Word format, which is annoying, to say the least. The workaround is to save them as openoffice documents, and use NeoOffice if a M/S Word export is needed.
