Agreed lol. Also as the OP let me mention what I did. Basically books cost money, I have no money, therefore no books, so instead I just hammered away at grammar and reading and now just read Ancient Greek direct. Which is handy because I’m a second year.
Non intelligo. What do you mean, “necropost”?
According to Wikipedia, it’s just another term for internet bump, when someone
revives an otherwise dead/old thread, purely in order to raise the thread’s profile.
I don’t think that was your motivation, but they probably mean that you could have posted a new thread.
No harm done though! 
I’d like to thank the recommendation of Stories and Legends: A First Greek Reader, by F.H. Colson,
(1908 version @Internet Archive). A great reader so far!
I’ve always intended it much less technically than this. It just means that you start posting on a thread that was dead a long time ago. Chances are, the original poster and earlier participants aren’t even on the forum anymore in many cases!
