Definitely easy to do that. Especially when the trial/games often has a mechanic that encourages talking to a lot of other people. Which is nice as it gives characters a goal to go say hi to new people even if they might not normally.

Event Posts are usually things happening in the setting. Like when we get new characters, a post will be put up where they can intro themselves and that would be an Event Post. Bond posts are going more into specific game mechanics, mostly when someone goes 'hey, let's do this bonding exercise, but widescale.'

Also usually TDM's are early in the month but there is also this one from last month that people would be willing to poke, I'm sure.
