:Hi. As far as I am aware, you can write on your user page, if you wanted to. A notice might pop up saying; "Do you really want to recreate a deleted page?" but just continue.  Occasionally, pages are "salted" to make it impossible to recreate a page with the same name, but there is no reason to think that your user page has been salted. By putting Wikipedia:Userboxes on your userpage, you can say what your first language is, and what other languages you know.  I expect there are hundreads of wikiboxes to cover all sorts of hobbies and statements.  Sometimes when I have seen an appropriate wikibox on a user's page, I use it for my page.
