Don't know if it's any consolation, but I got one of those letters back in 94. Having been turned down flat on my first 2 applications I was pretty happy to be put into the sift. Back then it took them 7 months to decide I was worth inviting to OASC and another 10 to decide I was good enough to join.
I know the whole thing totally sucks when all you want to do is get your mitts on a Tin Can, but it's worth it if/when it all works out. Best of luck to you all.
