C# List management and texting interface project completion

This is a C# winforms application with a mySql back end that is used for user and list management, and being able to send and possibly receive/forward texts either to the entire user base, specific lists or individual users. The code is about 75% complete, there are a few things that still need to be completed: 1. List management tab completion - assigning/removing users from lists 2. Creating events and assigning users to events. 3. Text send interface - all facets (This will be using the CellTrust service, API documentation will be provided). In addition, possible code optimization, although this is not required and should not be considered for the purposes of bidding.
