Hi, Shringarey.
If you're keen to crit some stories, you can head over to the
Share Your Work subforums. Always plenty going on there.
To help avoid some common critting pitfalls (which are very easy to fall into) I'd recommend reading these threads before critting:
Some Advice for Newbies and
House Rules.
There's also the
Beta Readers, Mentors, and Writing Buddies forum, where people might ask for a private crit. You can also post there to let people know you're interested in critting stories.
If you want to crit other people who've entered
Write1Sub1, then there's a discussion thread in the social group (which i've just sent you an invite to) that deals specifically with that.
Happy critting
Izz
