Welcome to MiceChat Phonedave! This is a great place to discuss all things Disney. The people on this forum are great. This is the only place I chat and I have made some good friends, just through posting!
Welcome to VMK also. I, too have two kids, two boys age 6 and 10. They are not on VMK as much as me though! My 10 year old likes to talk to people and thinks the "taken" is funny and doesn't take it seriously. My 6 year old can't read well yet and the words on the screen don't seem to bother him since he can't read what they are saying. I'm sure people on VMK may think he is rude, but it doesn't phase him. (His name is YodatheGreen and the my other son's name is GenKenobi.) He just likes to play the games and then spend the credits on his room. It's all harmless. I would encourage your daughter to play. She might like it. The Jungle cruise is fun for kids. They get to "take" pictures of animals. It is Jack's favorite game, along with Pirates.
My character, Sable, doesn't seem to get asked "taken" very often. But when I am my husband's character, Aviatorman, I get asked all the time. It must be a girl thing to ask the boys. I just say I don't do taken. If they ask why, I just say I'm not into it. A few girls say my character is cute (he's blue) and I love responding "Thanks, I was drawn that way." Most don't get the Jessica Rabbit reference, but I think it's funny. I mean really, it is just a cartoon character afterall. (Unless you're part of the Blue Man group, not too many people running around the color blue these days.)
Anyway, don't let the kids bother you on VMK. Keep an eye out for our next MiceChat on VMK. You can then meet us and make us your friend. But whatever you do, don't mention MiceChat on VMK. You will get banned. Trust me on this.
Again, welcome Phonedave!
