I'm sorry if this is already a thread, but I searched and couldn't find one so..
My laptop is messed up and I was gonna use my brother's old one until I can get it fixed, however I thought I saw somewhere that you had to notify one of the admins if you were going to go on Sylestia from another device. I just want to know if this is true, Do I have to PM one of them and tell them that I'm just using a different laptop? Or, Do would already know already?

I'm not sure if I am going to use it, but in case i need to I wanna make sure i'm not gonna like get in trouble or something

No, you do not need to notify the administrators. You probably heard that there's a safeguard in place that logs a person out if they are using a different IP address. This is to prevent others from using your account; however, it can become an issue for people who use different IP addresses frequently, so there is a way to disable the feature. You can either add the IP address of your brother's laptop to your IP Whitelist, or you can press "Disable Feature" on the same page.

Oh, alright
Thank you so much for answering ^^
