Lots of updates today, which mostly affect the text input screens: anagrams, no letters, initials, 5050, no vowels, no consonants (and their match equivalents).
The text versions of these screens now have on-screen letter buttons / keyboard (see above), which can be used with a touch screen, or clicked with a mouse, or used on an interactive whiteboard. BUT you can also type using your device keyboard if you're on a desktop or laptop computer. AND if you're using an ipad, ipod touch or iphone, you just need to click the word to make your device keyboard appear.
