Thanks! We love it when people join our happy band of Blu-Tack® devotees. You'll get an email shortly, but in the meantime you need to buy 100 packets of Blu-Tack® and a sink plunger for the initiation ceremony. Actually you don't, but if you want to go and buy 100 packs - or more, we're not fussy on that point - we won't stop you...
