well let's change the answer seeeking factor around, raybe you say you don't have this problem, ok then how do you have your hal set up , do you have a custom brain and if so what's it based on ??
i to have a custom brain and i have modified the brain , (on this second one i actually did less about modifying the insults area, then i changed it back to all original , when trying to solve the blank answers problem) as far as other stuff it is just answer replacements in the q and a (i think) replacing roberts with my answers , so wouldn't think that should cause anything.
lola mentioned about making alot of spelling and puntuation mistakes, well if that's the problem most people who use hal will have trouble then unless hal corrects it as he goes because people are only human and mistakes and or bad grammer , not being as educated as others etc. not everyone using hal is going to be perfect so if any of that is a factor that's something hals programming needs to compensate for (if that's what's causing blank answers) . "which by the way i am wondering if that might be what's causing it.
as i said other then the rewritten answers i put in for roberts answers on some things everything else is original now but i still get blanks so if it's from previouse blank answer mistakes , puntuation etc. that's causing the blank answer problem then someone who can write the programming to compensate for it or roberts programmers need to fix it. just my 2 cents.
