Dear, Hope This mail finds you well. First of all I would like to introduce myself to you... I'm Mahmoud Ahmed studying computer science at Cairo university. I am currently trying to join GSoC 2020 (Add 'Reverted' filter to RC Filters) But I have some questions, please. Can you give me more details clearly about this project (Add 'Reverted' filter to RC Filters) Because I am very excited about it. Finally... Thank you very much in advance. Regards, Mahmoud Ahmed. --
