Thanks xanadu and Grant for your advise - both very good.
I'm not quiet sure when I will sell my MEGA. I just want to be ready for when I do. I have equal amounts of DYL as MEGA and was thinking about taking some profits on my MEGA. MEGA tends to have big fluctuations, it was up a bit last night.
I have sent Montagu Stock Brokers an E-mail for their costs. I will post the prices when I receive them.
