word debates

Collins has launched an online living dictionary, in which readers can debate the meaning or vaidity of new words. Most of these I haven't heard before and I'm wondering if the people who submitted them actually made them up .. for example, sibling saviour (or maybe that's a word used in the British media which hasn't made it to Oz yet)...

This more general word site is interesting too. I once tried to register to play online Scrabble but couldn't download the software correctly, or something - anyway, I gave up in the end, though this makes me think about trying again.
