Fingers crossed, I won't end up like last time and removing everyone I wanted to keep and vice versa!
All done - I've been removing LJs that the user now has a new one too. I removed the wrong one, please tell me. Also, please check if we are mutual friends, as I found some people who I thought were but aren't.
This has been purely to tidy up my list, NOT because I desire to be rid of anyone.
