I'm just checking if it [/b] works properly. (apparently not, parser gets confused about mismatched tags)
You provide invalid input, how do you expect the parser to handle that "properly"; instead try providing proper input. :)
Ideas:
- Allow "short tags" (mostly, allow "[q]" instead of "[quote]".
- Allow "[quote=some text]" which adds "${some text} wrote:" above the quotation.
Not sure whether these are options you can simply enable (easily doable) or whether you would need to change the code for that ("not at the top of the priority list" to put it mildly).
