I think there's only this one "live" at the moment! Certainly if you go searching for them, there are a LOT of historical ones.
The best way to deal with that, is just not to read the threads. Honestly, if you stick around, live feeding is a topic that's raised from scratch once or twice a year - sometimes more. And yes, the same discussion ensues each time.
Wait until you see the recurring discussions about keeping more than one Corn per tank!
I've been a member here for years and I've learned to exercise my self-editing powers. If you feel as strongly as you seem to, that's the only way you'll stay sane! You'll certainly get no joy from expecting other folks to stop creating new threads about topics which bore you, or telling them not to contribute when these threads are started.
Oh I don't mind the topics starting and the arguments being made. I just hate when it becomes a circular argument, no matter the topic circular arguments just annoy the hell out of me.
Normally people don't even realize they're in a circular argument though, i've been in plenty and until its pointed out to them they'll keep it up. I mean look at it, we've moved on from a circular argument about snakes to talking about dog behavior.
