How to make a purchase in the Havven eStore? Where can I find a guide about this feature?

We are excited to announce a confirmed launch date for nUSD, the stablecoin in the Havven network. nUSD will be launched on June 11, and will offer a decentralised and scalable solution to a significant problem in the blockchain ecosystem: price volatility.

The release of nUSD will mark the launch of the Havven payment network, which uses a novel stability mechanism that rewards havven-holders for providing stability to nomin users. nUSD will improve an ecosystem that has great need for a secure medium of exchange — we have already announced partnerships with intimate.io, Swapy, and Deconet, all of which will come to use nUSD in their platforms.

Delivering quickly on the milestones detailed on our roadmap has been a key objective of the Havven team. As per our roadmap, nUSD will initially only be able to be issued by the Havven Foundation. The development team will continue to release new network features until the public issuance of havven-backed nomins becomes available in Q3 2018.

so does anyone know when havven-backed nomins are being released?

Is there a video anywhere that explains Havven so I can share it??

Hello, I want to tell you a little story about how Havven treats its partners and its obligations. Sorry for bad English.
In early February, I joined the Havven bounty campaign on BTT. Every week until the end of the campaign I have met all the conditions and laid out the reports in the topic on BTT. Accrual stacks checked in the table of participants of the campaign. the Campaign has come to an end, announced the pending payments: https://bitcointalk.org/index.php?topic=2617632.msg31294642#msg31294642   
After this post, I, like other members of this forum, repeatedly asked questions. No answer was received. After some waiting I got an airdrop of 18.8 HAV, but the payment for bounty never came. I appealed to the administrators of the official Havven telegram chat, they did not want to talk to me. I forwarded a copy of the message, which indicated that if I have not received payment - the problem is on my side. In the end, the administrator @Arete2 said that personally to communicate on every issue with anyone he did not intend. And said that the payment I receive, because did not fill out the form sent to me by mail on February 26. After that, I was no longer answered:

The postal address I registered for the bounty campaign is my e-mail worker. The main activity is to invest in ICO. All mails which I receive, is checked daily by me. The spam folder is also checked. So I confidently declare that on February 26, letters from Havven on my email address didn't come. The last letter was received in early February.
As I understand it in Havven no one is interested to solve problems. Chat with me just did not want(I was talking to different administrators) My last post in the BTT Havven thread: https://bitcointalk.org/index.php?topic=2617632.msg32839941#msg32839941
In support of their words, I can provide copies and screenshots of my correspondence with the administrators and my messages in the official thread of the bounty campaign Havven.
It's just a hoax. Also I have suspicions that my tokens could be appropriated by someone from administrators of bounty campaign.

hello, can somebody give me information about aidrop? does they have or still not? thank you
