2 informations :

- It seems that https://yenten.luckypool.org/ IS DOWN !!!!
 I have got the following message: "We are investigating issues in the backend. Your shares and hashrate are safe and we will fix things ASAP." BUT I think they sent me my coins just before as I just receive some coins.

-Regarding the wallet that require to send a tweet - I have just done it, it works: I receive one coin ( thanks !) BUT for an unknown reason my tweet cannot be found when I search #yenten in Twitter .
