Every lernu! page has a menu at the top, a language menu at the top and to the right, a dictionary, an instant messenger, (if you are logged in) "My corner" to the right, and a comment link and sound-player at the bottom right.
Here at "Help Pages" you will find explanations of how to use the site's various tools.
lernu! is a multilingual website. You can change the page language with the drop-down menu, on the right hand side of the top of the page. When you register, you choose your preferred language (that will automatically appear when you log in to the site).
Because lernu! is constantly evolving, it sometimes happens that some translations appear later than the others. In that case you will see the text in Esperanto, but if you want you can easily switch to another language by means of the appropriate drop-down menu.
Your comments are our most important source for determining in which direction lernu! should evolve to make it as useful and comfortable as possible for people who are interested in learning Esperanto! It doesn't matter whether it's a typo, an unclear translation, an overly boring lesson, misfunctioning of systems, or a missing word in the dictionary: feel free to send us a comment about it! There's a link you can use at the bottom of every page.
You can find explanations of other parts of the website here (check out the submenu at the top) or in the introductory pages in other sections (ex. "Grammar" or "Courses").
