CheckUser request 

Hi YM, a small favour please if you are willing. Can I get a checkuser for:

, based on edits at Talk:Sex and intelligence and particularly Talk:Matthew Johns. See this and this. 
If you can, you might also look at this and this as well, which I suspect is the same editor trying to muddy the waters the bit.

Let me know if there is anything else you need. Cheers, \talk
