All of them are now up (I think). Do go look and participate.
Note that for the Poetry Slam and some other constests, you need to be in Bombay on the date to be able to participate, but the regular contests like SMS Poetry, Flash Fiction and (this year) Essay, are open to all.
Update: There's also a Open Book Pitch Contest now. If you've got an MS, or a pitch to make but don't know any publishers, this is where you can meet scouts from publishing houses, among them Harper Collins, Penguin, OSian's Literary Agency and MIlls and Boon (I couldn't resist; but it's true! Also watch out for a post on these guys).
Go! Go! Shake your little flubber booties!
