I've sent a couple message with it and i like it so far.
Bugs?
I clicked on invite to a group and it took over 2 hours to process.
And Profile updates are very, very slow to refresh.
Do wish I could -
add friends from the app;
display in landscape;
control the font size, 8 pt. is very hard on my eyes.
See it here at iTunes Store
Good job TS!
