i have no issues with it. i did notice one very unusual thing thing though between the 2!
with the regex one... you can slip the command into a sentance, but your one .. we cant.
for example... with the regex one i can go /me ponders for a little bit and decides that we can voice timmy after all as he has earnt it.
and it will do it..
with your edit .. it wont.. it has to be a direct /me command
just found it out and surprised me :)
they both work as good as each other mind you
i have done a minor update on the check to make it a bit more secure :)
