This is probably a stupid question but I'm new to SSing and plan to only do it every once in a awhile to get some game avatars that I'm having trouble with. Is it ok to log into neopets when sending scores?
Do not log in while sending.
To add on to what Futurama said, by logging in while you SS, either the score sender or your browser will get logged out. If however you keep logging in to both the score sender and your browser, you would be able to do both at the same time, which is really bad because this is an impossible activity that TNT might freeze you for.
