I a day or so (from now - evening of the 22nd April) (teething problems now resolved) Simply browse to the TechNetPlus online subscription site or telephone 0800 281 221 and quote promo code UKITPRO3 - there's a problem that's being fixed as I type this.
Note: the phone number can only be reached from a UK landline/mobile as it's a freephone number.
Why might you want a TechNetPlus subscription? Well you'll get two free technical support incidents and download access to pretty much all of Microsoft's Infrastructure products including Windows Server 2008, Windows Vista, SQL, Office, Forefront, System Center, Sharepoint, Exchange, Office Communications Server, hyper-v (as part of Windows Server 2008) AND early Beta access to upcoming versions of products.
Note: there's currently a promotion on whereby new subscribers qualify for a 20% discount - using the promo code UKITPRO3 you'll get an additional 10% off.
The software is fully functional though is licensed for evaluation purposes only.
