Dear Neelam Shah,
Glad to see your note submitted via TheScian.com Contact Form. Unfortunately, the email you provided seems to be incorrect and my response to that email bounced. If you were wondering why I haven't replied, you now know. Here's my reply.
You asked if there is any age limit for the contest (from your email, I gather you are 15 years old and probably not sure if you can send a story to the contest). There is no age limit. Everyone who can write a good scifi story can enter the contest. There will be contests in the future too. But, don't wait. Send your story for the 2007 contest. You'll gain valuable feedback and experience, you could pleasantly surprise yourself too - either with a win or by having your story published at TheScian.com.
The contest rules are here.
In short, send a story not more than 6000 words and send it in simple
.txt format file (a file that you can open in notepad).
warm regards,
Selva.
