Been using Opera for many ywears now. Next time you log in to Noreast and enter your login and password, it should ask you if you want opera to remember this password. Answer yes. Next time, simply click on the wand (first icon left of the address window) and it will enter everything for you and you'll be logged in.
Yes, that will remember your login info.
But, if you don't want to log in and out you need to have noreast "remember" your info and you will always be logged on.......
