Before you start your log, it will be a good idea to right a brief bio... nothing much... height/weight/age/sex and experience if you want.
Tell us what your goals are and then just tell us session by session what you did and how it went/felt.
I'm going to encourage light discussion with in the threads... try not to get too heavy though... make a post on the main board if you think it is or I'll let you know.
For the sake of organising things it'll be a good idea if you use fonts etc so that we can differentiate from the log posts and the comments... write it in bold... a larger font or a colour other than black... it's your log so do what you want!
I think this is gonna work well, looking forward to seeing it put to good use.
