Yeah, the beginning in particular was kind of hectic because everyone was trying to introduce their character at the same time, so I def understand the struggle there. /: And essentially, everyone was talking to everyone. But now it seems individual, actual conversations are breaking off and starting to happen.
So if you're looking for some potential posting ideas, then:
1) Kuro cooked up some meat, so there is food on the table, and people sat down to eat dinner. Dinner is a great time for conversation. Kuro also dredged up his unfortunate past. So you could sit down and eat with people/start conversing with anyone -- for instance, talk to Kuro about the food or about the terrible past he just brought up.
2) Fianna seems slightly upset by something, so she took a plate of food and went to sit in the corner by herself. You could approach her and sympathize with her -- ask what's wrong, or just join her in sitting alone and being loners together.
3) A new character basically just fell in from the sky. You could post a reaction to that and approach the new guy. Any number of reactions would probably be appropriate. (This would also potentially be good because HelloBeautifulChild has a slower posting speed as well, so perhaps you wouldn't feel left behind if you tried interacting with her character(s).)
4) Be constructive and build another way in. Your characters all have special abilities and whatnot -- maybe you can use them in creative ways to weave them into the story.
And there are probably more 'ins' that I'm forgetting. Anywho, throwing posts out there to the whole of the RP generally makes it harder to get other characters to individually interact with yours, but if you can specifically address someone in your post, I think you'll both have better luck. :)) (Especially now that the climate of the RP has changed.)
