My Email is currently broken. I didn't break it this time, it's broken at source so I have no idea how long it will take to fix.
If you've sent me Email in the last few days, it's lost in Email limbo until I get it sorted out.
Hopefully it won't take too long.
UPDATE - Fixed, sort of. The .co.uk is still broken but the same Email using .com now works. Either I get the .co.uk fixed or I have to hunt down all those places I've used that Email and change them!
