What have I gotten myself into??

My mother decided that I should try and create a site.....one that was for "girls only".....older girls...no one under 18 is allowed to know about the site.....I thought..."hmmmmm....this has possibilities".  But what if I can't think of anything to write....or add....or display.....then I thought well what if I created a site that we could all have access to...that way if anyone wanted to add something they could.....this could be fun.....so until I get the hang of it I won't be spreading it around quite yet....however once I catch on....look out!!
