Users are actually remembered by default hence why there is no remember me option. The server is told to keep your session open for up to 2 weeks. Myself and most other users are kept logged in.
If you are being logged out it is probably because you are being sent to a different server each time, which can happen as we have a few web servers and depending on load you will get sent to a different one. The servers do not share sessions at the moment but that will be fixed in the coming weeks, as we complete the server system setup.
