I'm stealing this idea from The Bench and thought it would be something good to have here as well.
Read the rules before you ask for an address!!
1) Two requests per person per day.
2) Player must be retired. For active players, write c/o team.
3) Do not ask for superstars. Most superstars do not sign TTM.
4) Please include the sport and team of the player. This is needed because of players that have the same name. (For example: Dave Roberts)
If you fail to comply with these rules your post will be ignored and unanswered. Any members that violate the rules too often will be listed on this post and will not be answered if they make future requests.
Now that we have the unpleasantries done with, ask away and have fun!
Update 6/1/09: I will no longer be giving success percentages from SCN as requested by the owner of SCN.
