Just want to check this is still open to new characters before I start serious plotting.

Mateotis answered the question - you're free to join in and get a character up... as long as you ACTUALLY POST. We've had a lot of problems with people posting characters, being really into it, and then dropping out after one or less posts. 
IF you're actually going to join in, then you're more than welcome.
