I created a community for the "forgetful" people...umm , well, for me :)
I wanted a site where people could leave their thoughts and ideas. I use mine like more of a tracking thing really, like how I fixed a certain problem, or how I cooked a certainly meal. basically an extension of my head. I could just go to my site http://bill.checkmyhead.com and look the info up.
anyways, I think its going great, I have a lot of users, and everybody seems happy. Anyways, check out my main site and you can create a site if you want too :)
