Okay, my website revolves around dog sledding. Is is becoming really big, and I have had requests for an online training log manager. I would like to be able to have a program (preferably php), that will allow my users to enter training log info, like weather, miles, speed, and other training variables. I then want each user to have a list of all of their training runs, and then all of the users can view eachothers training logs and learn from them.
How should I go about doing this? It is really advanced for me, and I want to know if you know of any free scripts that might be able to do something like this.
Any help would be greatly appreciated.
