James, I appreciate your time and consideration on the matter.
This is by no means an emergency issue, but even if it could be put on a to-do list somewhere that would be nice.
It's a chatroom of philosophers. The current limit is 450 characters, which translates to only 3 or 4 fairly substantial sentences. It doesn't happen all that frequently, I'll admit, but the limit is something I've run into a few times. It's usually in the midst of developing an idea, and then I'm faced with an awkward decision of letting the first part hang as I finish up the second, or moving to an external word processor and doing multiple copy-pastes.
Then there's the issue of quoting itself. Wanting to quote text from an outside source is almost going to guarantee at least 3 or 4 copy-pastes.
And a list? Forget it. There isn't even an ability to "shift-return" to the next line in the message box.
None of these are catastrophic on their own, but I think hands down the best choice is to have no character limit (and the shift-return wasn't something that even occurred to me til now). I can't remember it ever being abused prior, so I can't find a downside.
