You can set your other accounts to follow your main account as proxy, and then when you vote with one the others also add their voting weight.
If you use Keychain, there is a 'Governance' section under 'Menu' that has a 'Proxy' tab that makes it easy to manage.
Oh great, I didn't know that.
My Actifit-Account doesn't have that much, it wouldn't make any real difference but it is good to know.
Thank you :)
