very, very sweet, jc!
two quick fixes:
1) in the instructions, you say to add "ACTIVE_TOPICS" to the language file, but the code you developed refers to "ACTIVE" (so, either the instructions have to change to "ACTIVE" or the coding has to change to "ACTIVE_TOPICS")
2) in the html itself, there are two unnecessary "colspan" references, the first and the third. only the second reference should be in there.
and, just to note, i'm running this on 6.4 with no problem!
i diggit! thanks!!!!
