I would suggest actually RPing. A response like "Let's fly!" is rather pathetic coming from the topic starter. As it's YOUR thread, you're held to a high standard than the rest of the players, as they rely on you for general direction and plot advancement. I understand that not everyone wants to type out 3 paragraphs a post, but I can assume that most people would prefer to read a few sentences over a single statement.
You need to emote, not state. It’s all to easy to have your character say how they feel, or use punctuation to accentuate it, but explaining it, telling the story of the emotion will draw people in.
‘Hunter peered out over the cliff’s edge, the sky stained in red and orange as the Dragons before him danced in the wind. Such a sight, the likes of which he had never expected his eyes to meet, left him in awe. ‘
Something like that. You need to treat each post like a blank canvas, and use the words you type to paint the scene of the moment.
