Still seeing quite a few questions so here are a few tips / details / hints
Times are in MST <- my timezone
Daily Codes are every day.
In the morning, I set up *
almost all the codes for the day, and put out the renamed signs/invul monsters/ etc
Mirc is the last code set up and then it's posted in the mirc chat.
The mirc code is the morning code and expires at lunch
All other daily codes expire between midnight and 2 am or so the next morning.
* the afternoon forum code is not posted until after lunch
* the evening dungeon sign is not put out until after 6:00 pm
Codes will be obvious. They will be multiple words with no spaces or words with mixed random letters and numbers after them.
I do not replace letters with numbers in words.
Signs and items used in the event are colored ice-white so they will stand out a little better
Town sign codes are on ice-white signs that are placed above or below a normal town shop sign.
Invul monsters are colored a horrible yellow color so they are obvious
For other codes
They can be anywhere at any time and are generally not announced. Anywhere means anywhere. Items/signs just randomly in the word can be renamed with a code. They could be on a creature or animal showing up as loot (written in a book). Some npcs will give hints instead of codes. Figure out the clues to find the code. They could be announced in a limited area. etc etc etc
The best way to find them is to play. Try to get around the shard as much as you can. Take part in events and activities that occur, even if it's just to check it out (for example there was a code on a sign at the 1v1 last night. You didn't have to join, only stop in)
As I've mentioned, "What say you?" is an important phrase. Talk to codekeepers and other obviously, oddly-placed npcs you may encounter
hmmm...
think that covers most questions (that I will answer)
