As long as you keep WANTING to come back To NG, either to B/P, browse the forums, or just generally watch and play flash then yes you belong here. I suppose you're thinking now that you're older, getting a career, especially one where you'll be teaching people who are more the typical 'NG age', you feel a bit less like you belong here.
I'm sure no doubt when you do get a permanent placement, your time will be more precious, what with grading and everything, plus time devoted to your girlfriend and everything else life throws at you, and then slowly you will find yourself using this site less and less until it stops altogether. That will happen regardless (lets be honest we're all going to grow out of this site eventually).
So yes my point? Which even I've forgotten somewhere..
As long as you keep wanting to be on this site then be on this site. When you're ready to leave it fully, you'll know, or you won't know, it'll just be automatic. So no need to worry I guess.

You still belong here - it's much better for me to pass an active user for Blams than a lazy, inactive one!
But in all seriousness, you're still a member, regardless of whether or not you fulfil all that you did back in the day.
