It seems that if a signature has too many characters clicking Update Signature will fail to update the signature with no error message displayed.
To reproduce, try adding this as a signature:
**NA-W Organizations:** [Advanced Technology Prevention Society](https://chroniclesofelyria.com/forum/topic/25985/Advanced-Technology-Prevention-Society) | [Banking Guild of Angelica](https://chroniclesofelyria.com/forum/topic/25986/Banking-Guild-of-Angelica) | [Gold Bank](https://chroniclesofelyria.com/forum/topic/26004/Gold-Bank) | [Golden Dragon Mercenaries](https://chroniclesofelyria.com/forum/topic/26003/Golden-Dragon-Mercenaries) | [A Glorious Death](https://chroniclesofelyria.com/forum/topic/24618/naw-a-glorious-death)
**Friend Code:** D12A20
This should fail with no error displayed. But if you use URL shorteners on the links it will succeed:

Also of note, I'm on Firefox 47.0.1. I haven't tested other browsers.
Also as a supplementary bug report, code blocks go completely off the page in a post's preview and the post itself rather than wrapping the text within the preview area.
