Learn from the mistakes of others

I am not at home for the next few days, and haven't been since last evening. I am cat-sitting, and son-saving, whilst L is away in Melbourne.

I am curious to knwo if anyone knows of an LJ tool that will enable me to switch between my two LJ accounts so that I can post to either at will without having to either run two separate copies of semagic and survive the havoc of random logouts and logins and other mayhem.
