I think your post is very good David, but I know that those things are being done here at Terry's. Time and Time again, regarding drawings, more information is requested, additional drawings are requested to clearify... Possible mistakes I can read are pointed out to the posters, I see it time and time again from experienced people here regarding plumbing. I really think, the plumbers here are very meticulous in their answers to others, they really go out of their way most of the time to make sure they are right on the money; and what I find astounding, is the fact that other plumbers/their peers are also, either giving their opinions, too. Wow. Where else can one get that? That is amazing to me.
Grumpy was right on one thing for sure, where else can you go for free advice? Absolutely, right.
I can't imagine the amount of work and time, it must take Terry to do what he does with the site. I wouldn't have the energy.
Everything to me you posted is right David, but I think all those things have already been addressed to posters so many times. If Terry wants to add a page that is great, but to be honest, in my opinion, he doesn't need it. That could be also, just another thing he must take care of.
So far as the money, save Terry his time, and send it to me.
