Thanks, Marbux.I didn't find the spellchecker for firefox previously. I've just installed from your link. Thanks. However, I thought in a single server side solution would be nice... (mabny of the students' homes, or even computer rooms in educatioanl center have only Windows Internet Explorer installed, for instance... :-/ )
And yes, TikiDav solves partially one of this problems, if all students use it... (not yet, and TikiDav still bug fixing and evolving to make it more available to all OOo clients, Web servers,etc.). I'm not a coder (Javier Reyes is "the" TikiDav coder, I'm just tester and potential "user").
