Summarized: The NTTac & Dialways plugin is a cool software integration.

Once set up, TacMessage is ready to serve seamlessly. The user's connection to the internet is monitored, and messages are sent out based on the amount of credit remaining in the online account. This is a fantastic feature for professional users who require additional information beyond their remaining credit, such as IP allocation.
One unique aspect of TacMessage is that it does not require any installation on users' computers. As long as the user is on Windows XP or 2000, the software will work without issue. For those using Windows 98, activating the Pop-Up Message should not be a problem.
Overall, TacMessage is a reliable and intuitive software solution for tracking online account balances and providing essential information for users. It is a convenient solution that removes the stress of tracking internet usage for users and providers alike.
