As my teammate said here:
We will have many bounty campaigns (signature, newsletter, blog, community management) but not a Twitter one. Wait a few days please!
So, I asked to join Twitter just for the latest updates, not for bounties.
Lots of bounties are going to be available. Please keep PMing me if you are interested in translation/community management bounties and I will forward it to the team. If you have sent to me already you do not need to again, it has been forwarded. Thank you!
