Sweet! I see from the screenshots that the app can support HTML formatted text. Will special codes need to used?
Taylor Dec 3 '12 at 18:28
The app will support the standard bolding/italicizing/strikethrough of text that can currently be done with existing Google Talk clients (GMail chat, and desktop GTalk client). We however also give you the option to have image URLs displayed inline as you see in the screenshots. In addition to this we have added the ability to underline text, as well as to preserve the format of text as with using <pre><code> tags in HTML. This last bit is a new addition and we have not made screenshots to demonstrate it yet, but there will be a menu in app detailing how to perform these text manipulations.

Added two new screenshots demonstrating how to format your message text to share code snippets, etc.

Does this implement the low-bandwidth guideline for internet apps, if the user chooses to do so? I don't want to be wasting my bandwidth on this app, especially the chat protocol.
Taylor Dec 3 '12 at 2:23
There is no wasted bandwidth. A Push Notification will be sent to your device only when you are receiving a new message from a contact. There is no active connection or socket that is maintained in the app, so it is bandwidth and battery friendly. On a side note, is there some specific guideline page you are referring to for bandwidth?

Hi Taylor, You can see the metered connection options available to developers of Windows 8 apps here: It's pretty cool they allow you as the developer to throttle your app in cases where the user is on a paid data plan, over/under their data limit, etc... So you could shut off features or everything depending on the situation. Will be nice to try your app, looks nice in the screenshots.

Oh okay I see what you are talking about now. Currently we have not added mechanisms to respond to the user's active connection, but we plan to. Thanks!
