Hi,
thanks for answering.
I have made plenty of changes to roundcube for my project. Now i must merge them with this nightly build to have the html editor. I have never done that and i am scared to death. I am reading now a svn book.
I see that the app.js has been intensively modified (500 lines removed) and I have added 700 myself so it is going to be a nightmare.
Well. At least from this experience i will get a good idea about svn (hopefully).
