I know people aren't really interested in a switch, but I have been on there a lot more recently since GPM has been so slow and I wanted to let you know of some of the awesome features; just in case it might sway your opinion.
Pros:
They have a mobile app, and a mobile site that is very user friendly from your phone.
Notifications when you are mentioned in a thread or quoted, so you can keep up with the conversation.
Easily jump to the last page of a thread from the main screen instead of having to go through all of the responses
There is a lot more activity, so when bored you can check out other boards like ML and MM
Mods run the boards, so we can create our own with little effort
Cons:
Not as pretty as TN, but the platform is much better in the background
Mobile app costs money, and is still having some kinks worked out
Mobile site shows who last posted on a thread instead of the thread author
Unsure how to upload pictures, but mostly because I haven't tried.
I am sure there are other pros and cons but these are the ones I can think of off the top of my head. Consider it?

I'd go if you ladies go. I hate being bored over here.
Me too please. When did the FB move happen?
I really should reconsider my anti FBness.
After 31 cycles and two losses, we've been blessed with a healthy baby girl!
