Last night, we made substantial upgrades to our servers and everything worked very nicely.

I want to publicly thank my team. They worked very hard to make this transition as smooth as possible, and it has been. Only a couple of minor issues this morning, but no real troubles. While upgrades are a normal part of maintaining any web-based services, this move was of substantial size and complexity and they performed flawlessly.

We made the upgrade to preserve our core purpose: to provide a fast, easy-to-use web application that delivers text messages to your contacts as quickly as possible.

We remain excited about our responsibility of serving your group text messaging needs.

In TXT Signal, you can customize the primary contact group names to fit your needs.

To edit/hide/unhide contact tabs:
1. Login (www.txtsignal.com)
2. Click the “Settings” tab (upper right)
3. Click “Change Tabs/Group Names” (link on the Actions menu)
4a. Edit: Pick from the list or select “Add a new name” to enter your own
4b. Hide: Select “No” for displaying the Contact Group
4c. Unhide: Select “Yes” for displaying the Contact Group

Bonus: When you customize your tab names, the custom name change items on the screen and provides context to the actions you might need to take.

Confidentiality

We receive questions about whether txtsignal.com sells any contact information to third parties, marketers, etc.

As loudly as we can possibly type, the answer is NO!

And, we have spelled this commitment out in our privacy policy:

TXT Signal does not sell (or re-sell) any mobile contact information contained within any client account. As noted in our Client Data Storage policy (below), the data is the clients and can be exported at any time.

Security

We also receive questions from time to time about the security level we use when contacts are being entered. txtsignal.com uses 256-bit encryption (same as online banking) on any page where contact information is being viewed, added, or edited.
