I am in the site right now....
There is a link to SP balance and instructions on how to wire funds. If you scroll down the page it gives you the option to WD to your egold or ebullion. I could not locate an option to re-invest all or a portion.
Here is what it says on the site:
You can withdraw SP Available balance via E-gold or E-bullion. It takes 5 business days to fund our account and to make payout.
ORDER TO E-GOLD ACCOUNT# XXXXXXX
ORDER TO E-BULLION ACCOUNT# XXXXXX (In addition to the wire option)
Good luck to all. This has been one heck of a journey for us all!!
