As you may remember from previous blogs, MM is meh bestie on the internet. *I just wanted to say that*
And also, I'd recomend getting a blog, as you can make sure you spread the message across about what it is your subject is ( mine is random really but it's for people my own age and a little older). Ya know, so you won't get people replying as if the were talking about science and stuff, not sure what to say.
I'd recomend it for nearly all ages (maybe not girls of 5 or 8). Once you understand the ground rules, it'll be grand! :)
