The current limit is only an annoyance when it comes to hyperlinks. A non-vip Sig should be functional but not fancy, because vips pay for fanciness rather than functionality.
2 lines of text, and 3 lines total including bb code is completely reasonable.
Supported.
people like me cant buy vip where they live so i'd like if they make it atleast 3lines and 300 character for non-vip people
