Thank you very much for your interest. We sent acceptance letters to the corresponding author of all accepted papers. Please check your paper condition, please visit https://isites.info/Paper/Index web page. If everything is ok please wait until symposium day and prepare your presentation (max. 15 minutes). But if there is a problem please fix it by the below steps. Please ignore the certificate column because certificates will be given after your presentation. - If your paper format is wrong please correct it from https://isites.info/en/Page/Index/5/16 and upload your final paper from Easychair. This is the most important step because we can't publish wrong format papers. - If you still didn't pay your Registration fee please visit https://isites.info/en/Page/Index/5/15 page and pay your registration fee until 8 OCT 2021. Please don't forget to pay in early registration dates. Early Registration Until 30 Sept Late Registration (1 OCT - 8 OCT) - Our Symposium paper page limit is 10 so if you have page extension you should pay extra for pages. Please check presenter's name and inform us by email if the name is different. Because we prepare all printing materials according to presenter name. We greatly appreciate your cooperation in these matters. Thank you again for your contribution to ISITES2021. All presentations will be online.
