DL13, I want you to know that we'll miss you if you go, a lot :'(
This, coming from OVERGRO, is a great thing. Next time you're in Canada, keep in touch with me - perhaps by email or something. [In a non creepy way]
I can't force you to do anything, but as you can tell, even if Smogon no longer appeals to you, you shouldn't deactivate your account simply because of all the people that would miss you. :(
I know all about having "bigger fish to fry." I'm actually pretty successful outside of Smogon, beleive it or not :) But I keep in touch here because I'm now a part of a community - even if everyone here is more interested in "spam" than intelligent discussion (intelligent non-pokemon related discussion even).
De-activating Smogon is kind of extreme, maybe swing by once every two months or so because we miss you around here :)
