Old Hand Returning to the Fold First off, hello everyone!

I'm an old hand when it comes to fanfiction, probably writing some 15-20 years ago, ending sometime in 2008 after life intervened. 

But now there are communities and such like this one and I thought I might ask if anything has really changed in the world of fanfiction writing at all, or if it's still the same as it's always been, just a bit more organized and expansive both.

Anything I should be aware of or on the lookout for... or just do as I've done, just with some newer interests?
