Alternative Writing Sites

OK, so don't get me wrong I really enjoy Mibba. Apart from the quietness which seems to be more apparent from reading other blog posts.

But does anyone know of any other writing sites, specifically to read and write fan fiction. It seems as though here not much tends to get updated, which is a shame because there are some talented writers on this site!

I've had a look at fan fiction.net but it's saturated, in my opinion. And I took a look at Wattpad but I didn't understand it - but this is probably my fault as I'm on the mobile site as opposed to the desktop site.

Suggestions would be helpful, thank you
