I received my 2000 shares also and wont be selling.
The share certs are being sent as the capita registrar nominee accounts are closing due to costs. This coincides with an 11:1 consolidation to shake off small holders.
Most people sold from their nominee accounts a month ago if they were going to bother there will be no impact on the share price.
My advice is tuck them away for 5years plus and you will be pleasantly suprised when you return.
