Dear Elisa, I am Neli Marcheva from LEMARIT GmbH, a registry service provider and an ICANN accredited registrar. Our team has experience in developing our own registry system and successfully executing multiple TLD transitions in the past. As a first time RSP we went through Technical evaluation, RST and the additional first time RSP testing (simulation testing). We believe we can contribute to the upcoming IRT sub-tracks: Topic 6 | Registry Service Provider (RSP) Pre-Evaluation Topic 39 | Registry System Testing (RST) Could you kindly add us to the mailing list for these sub-tracks? Here are the relevant contact details: Neli Marcheva - n.marcheva@lemarit.com LEMARIT registry services email - lrs@lemarit.com Thank you. Best regards, Neli Marcheva
