Welcome back!
I don't know if you can welcome yourself back but I sure have. I found a random email where it said someone commented on an old post. It was obviously spam, so I thought I would come and check the old gal out. I'm surprised to see a few people still posting and some communities up and running. I think coming back to Lj is a good idea. There are a lot of things I am into, like movies etc. that just don't fit in with any other social media platform at the moment. Just give me a bit to re-familiarise myself and I'm sure I'll have things up and running.
