My Trade List
Features:
Pending Trades
Many options for altering list
Past Trades (Unalterable, but allows member to view the trades and provides an option to print necessary forms for those trades if needed)
Here is a VERY rough draft of what it could look like (doesn't have all features listed above because it was created in a spreadsheet program, so you'll have to imagine things like a 'print forms' button, etc...)
Plant Database Appearance Possibility
