I think so also.
Sometimes it happens but also (if you write a pm. to the principals providers or if you write a comment in the TV Series saying you want work in xxx season) they can answer that in that moment they are too busy and you can go for it.

Anyway, usually an user who begins posting a TV Series he continues working several seasons.

You'll always find work to do in 'new movies' or in 'new' TV series that aren't already listed in the site.

And about the summer, also the best for you (count down for me in ONLY two days :sun: )
