Hi. I'm glad to have maybe been the first to test your plugin.
1)It's amazing.
2)Love the admin integration.
I have carefully went through and tested your commands on a TF2 Server.
Things I wish to recommend in a next version:
sm_alpha - Is there an option for normal? Is 255 normal? Please make that a little clearer.
sm_colorize - May I request that "Normal" be added to the menu of colors, because when I issued /colorize @me "normal" in chat, it worked perfect, putting me back to normal color.
sm_ff - Great! If I were you, I'd mention it's in the Server Commands menu, took me a while to figure that out. ;)
sm_happy - Great! I replaced the current lines and they worked out fine.
sm_invis - Great! Hopefully it's not abused by too many admins ;)
sm_tele - Works great as well, and seems like it's the same one as the "Admin Teleport Plugin," correct?

Overall: I definately approve of this plugin.
Do your job official approver people! Awesome job on your first project, you two.
