So I'm unable to use the graphical client as I'm using the SVN.
I have 20 btc somewhere belonging to an account I don't know. How can I get a list of all the accounts in my wallet?
Is there a way to send X just from all accounts?
The SVN version includes the graphical GUI.
Just use your wallet with any copy of the client and your coins should be available, accounts are irrelevant here.
