The Finn speaks the truth. You had better watch your ass. Though.. gotta ask.. what state are you in? Is it either California or Washington state? Don't name the state, but say yes if its either of those two.
Might be some room to manuver legally for your brother.
Unless you brother has some serious legal clout I doubt the emancipation route is going to happen anytime soon.
As far as writing your brother I understand you have to have some code number or some crap like that to put on the envelope. If this is true you merely need to get ahold of this number. I'd suggest volunteering to take the mail to the post office on a regular basis or something like that.
Not sure what else to tell you. Normally we have one or two SCL survivors floating around, but they are prone to the flaws of humanity and have been known to get a life on occasion. There is that little toad Kevin over on
www.antiwwasp.com. While I think he ought to have his face rubbed in horseshit he does know SCL. He might be able to confirm the envelope code business.
JUST don't let him talk your parents into sending your brother to Magnolia Christian Center!
