Textareas may or may not wrap text. When a textarea does not wrap text, the user is likely to hit the return key in places where a break is not wanted.
That was really my main beef that I had for a long time. Now that I think of it, this board has alot more posts of code than others, and code on other boards has wrapping problems, but requiring everything else to be tagged still seems unnecessary.
That specification you quoted is interesting. I've suggested things elsewhere that would add less structure to HTML. In this case, I'd go for consistancy. I think I'll change my script to support the absence of those semicolons.
I don't intend to be a full time troll, and I don't take food from strangers.
