For a project I need allow LaTeX input from a from website's users. I want a light weight LaTeX Editor that I can embed in my website and help them to write and edit their documents.
I want this editor be like LyX - i.e. WYSIWYG(M), tiny and of course open source - if it is possible. If it isn't, I want it to be as easy to use for authors as possible.
Is there any kind of editor like that?
