Posting Order and Moving around on the Map

I figured I'd bring this up to everyone as we need to figure out the best way to handle movement and posting while text role playing. At times, things get a little chaotic with everyone posting at the same time and moving around. I try to keep up the best as I can, but sometimes people's post get missed. For passive, non-battle, situations I can continue trying to handle it without forcing a post order. We can do a post order if you guys want, or try something else if you anyone has any ideas. If you feel the way its going now is fine too, we can continue without any changes.

A post order would slow things down, and limit random dialogue while others are typing. The positive to this would be that it gives everyone time to type something up and feel they have a chance to express their ideas without someone scene stealing. The problem is that not everyone has input during situations and like I said it may slow down the experience even more.

Another drawback to text role play, is moving your token on the board. Generally, in voice rp, you just move the token around slowly and are able to quickly vocalize if you want to do something. In text, I believe the best way to handle movement is just restrict it to your characters round move limit (Generally 30ft). Movement and post order may have to coincide when the party is moving through a forest or city. Mainly because if one person types faster and moves more, he could be halfway across the map before any of the party has decided how to move or act.

The party or myself as GM can decide on a group leader from time to time to decide where the group goes as a whole to move through quick areas where no threat or actions will occur.

So to close this post, the main thing I'm looking for is any input you may have concerning posting rates and order and how to handle movement better. Thanks for playing and posting!
