I think I may have got a solution. When you click on a tag button instead of only the closing tag or the opening tag appearing, print both the opening and closing tags with one click only and then the posters can write in between them. That would reduce (drastically?) the chances of there being no closing tags. That's all from me, what say you?
That's how they used to be on the old PT (pre-2004). People either put their text in them or didn't, but there were no problems with them being left unclosed.
Yeah, but with my suggestions, even the amnesiacs can have a ball.
