Hey, been doing this for some time now and never really posted a specific list of general stuff that Knights gain xp for.
so here:
mentioning home folder show in your sig
generally posting in home folder
tags received and tagging
kudos
"accepted solution" posts
posting in avatar submission threads (when we do those) and submitting avatars
participation posts in regular folder game/contest
posts in wiki thread
posting in, and/or making, episode discussion threads for those shows that are on-air
entry/contribution submission in wiki threads
posting a general topical thread in home folder
linking folder events, ep discussion threads, show wikis, etc, in sig
conceiving a folder event
and probably other stuff I'm leaving out.
this is besides the special "Knights" type games/events.
