New threads in this forum are to be approved by a moderator before they are displayed.
Trade shops need to approved by a moderator before they appear in the section, as you can tell by the description of the forum:
It's also mentioned in the rules of Trade Corner. So just be patient :)
Edit: Actually TF, the rules say to just be patient. TC isn't like OC where it didn't have a moderator so h-staff needed to be prodded every once in a while to check the moderated threads, it has 3 moderators that check regularly, so prodding them about moderated threads isn't recommended. Just wait.
→ On Thread Revival...
You may only revive your own thread. Do not revive someone's thread that was last posted in over a month ago.
Well, if you had read the rules of the section, you would have seen exactly what the stance is towards thread revival in the section (as well as had your question answered before you posted):
So you could have revived if you had wanted to. Chances are the message is followed by a redirect, I don't think they can control how fast it redirects to the next page. In the future if you're confused a skim over the rules of the section should point you in the right direction :)
