Here's how it works:
:sendim [Account Name]
--Sends an IM to that account name
:viewBlocked
--shows the people that you've blocked
:unBlock [Account Name]
--Unblocks the account.

Here's a snapshot, will probably be released on Era.

Thinking of adding more features, but here's a basic that you can use!
