Just in case some of you haven't also heard, until 1pm today UK time (Sat 27th June) you can also receive 20 free credits by adding the code (I've removed code now as offer is over) as found by fellow researchers in, I think, yesterdays edition of the Herald. It works as I tried it myself last night. Thanks to Jalkatz (from memory) , who shared this with me. Hope it helps others too, but you need to be quick.
