Thread not appearing

Hi! I tried to post a sketchbook on sketchbook forum. Actually twice, I thought I did something wrong the first time… Anyway, it has been ~24 hours since my first try and the thread is not showing up. Is there something I can do to make sure it hasn’t gotten “lost” or something? I read that posts should undergo moderation check in less time than that.

EDIT: Problem solved, the second attempt at posting my sketchbook has now gone through!

Hello, I’ve got the same problem. I started a thread yesterday and it still didn’t show up. Will it appear soon or will I have to rewrite it?
I also put a URL into the post although I read afterwards that I am actually not allowed to (I linked a YT vdeo showing what I am looking for). Is my problem connected to that?

Thx for reply
