I just start this account some days ago, and i try to join a signature camping (that accepts newbies), but they dont accept me beacuse i havent done a good post, so im a little confused here beacuse im not sure what could it be a good post (i know that ref links, spam, etc wont be a good post), not sure if it has to be long or just constructive.
Thanks for reading and i hope i get an answer

(btw i tried to search for similiar post but i dont find it sorry if a make a duplicate question),
