I run a free newsletter called Caferati Listings, which shares writing jobs, assignments, calls for entries and submissions and the like; basically, opportunities for writers. It has just over 1600 subscribers.
After a good run, I kind of stopped sending it for five years, but restarted it earlier this year. You can see the archives at http://groups.google.com/group/Caferati-Listings
If you have opportunities for writers you'd like to share, tell me.

(Boosts much appreciated. Thank you.)

If you'd rather not get in touch directly, you could also send tip-offs or submissions via this Google Form: http://bit.ly/caf-listings-form

I'm also trying to build a database of Open Mics in India and south Asia. Can you help? https://goo.gl/WREkNW
Open Mics in India

An attempt to build a comprehensive list of regular open mics in India. Open mic: a public event where individuals or small groups of individuals get short but equal time slots to perform works they have created themselves. This includes: poetry and/or music and/or stories and/or comedy. Regular: at least once a month. No curated performer lists, no panel discussions, no workshoppy events. This is about pure performance spaces open to all creators who seek them, first come, first served (prior sign-up is okay). You can reach me at @zigzackly on Twitter or that handle on Gmail if you have queries. If you'd like to help, please pass this form on to other organisers. The short URL is https://goo.gl/WREkNW This is the database: https://docs.google.com/spreadsheets/d/1wjrCWqyIyns5DZ3uiJ-7lMYQXTSeefo13FKkJtS85U4/edit?usp=sharing

And in fun stuff I kind of left behind but hey, this is a new world, this South Asia Literary Map. https://drive.google.com/open?id=1XdUoWM5By4uO_QdeHPfGmMWcGww&usp=sharing
