I think when I do introduce my characters, I'll just do my best to improvise with their interactions with the others. Stuff like "long time no see" etc etc.

I've done my best to read through most of the characters, but there is indeed a lot of content for this roleplay. So if I make any mistakes within my post regarding ANY of your characters, please let me know so I can fix it up. Even if I don't find the time to edit the post, at the very least I would like to be less ignorant for the next time our characters interact.
