soory, but as already mentioned earlier, I totally agree with what weltall stated.
there's absolutely no point in copy-pasting code to do the very same, again. it will not solve your issue as you'll still get OOC tells in whisper and it makes (the already impossibly hard to maintain) gui code just even harder to maintain - hence even more prone to bugs.
as for characters hearing you... if it's added as IC, it'd be *very* small, maybe 2 or 3 meters - that's absolutely nothing. try to drop an item as far away as possible, that's 5m.
that put aside: the say range already is quite small - adding a whisper command - fine, not that hard. but I really agree with weltall that some requests are just ridicioulus from an engine pov.
