Roxer is a pretty darn easy way to make a webpage. You basically put your content, including images off the web, into boxes and move them around.
I’m not sure if you can create a finished product that is comparable to some of the other website-makers out there (Paul Hamilton recently reviewed one of them called Webnode) , but Roxer would certainly be accessible to English Language Learners. Many of the other “easy” ones, I think, are just too complicated for English Language Learners.
I’d say Tumblr is still the easiest and best platform to display student work online, but Roxer is close behind it.
