@Bunnita When the RP first started there was a huge number of characters (somewhere around 10-12). Therefore they had all been split up into groups. Each group was assigned a symbol, so they could quickly identify what was going on with their character. Since then we've dwindled in numbers and consolidated into one group, thus the symbols have gone.
We may end up using them again, depending on what happens. If the characters split up the symbols will be used to identify who's where. I may even use them in this next post, to identify characters in different areas. Will let you know if so!
