There's one feature we wonder if you're planning (for moderators)...
The ability to change post authors. It would be very convenient for RPs when the one who posted the first IC/OoC/CS post leaves for some reason or other, as it means the remaining players can keep the RP running in the same thread.

EDIT:
Color codes when used after each other can erase spaces.
for example, other than adding the color codes, the below line is an exact copy of the one above this:
[color=ed1c24]Color[/color][color=f26522] codes[/color][color=f7941d] when[/color][color=fff200] used[/color][color=8dc73f] after[/color][color=39b54a] each[/color][color=00a651] other[/color][color=00a99d] can[/color] [color=00aeef]erase[/color][color=0072bc] spaces.[/color]

However, if the spaces are outside the color codes, they stick. As you can see below.
[color=ed1c24]Color[/color] [color=f26522]codes[/color] [color=f7941d]when[/color] [color=fff200]used[/color] [color=8dc73f]after[/color] [color=39b54a]each[/color] [color=00a651]other[/color] [color=00a99d]can[/color] [color=00aeef]erase[/color] [color=0072bc]spaces.[/color]

Oh and one more thing. After editing in the above, saving the edit let the color code selector remain visible. Thats probably a bug, right?
