I'm still kinda new here, but I have noticed some things common to most forums.
This isn't the most active board on the internet. This doesn't mean it's not a good board, we just have a comparatively small target audience. Not all the members visit 3 times a day.
Those who ARE here, are wiling to share their knowledge and experiences, but they have to read and think about the post first before they can reply. There's been times (on other forums) that I've read a post, thought about it during the day, and replied back later. I know that doesn't do much good if you need an immediate answer, but it gives a well thought out reply.
Links: Many people don't click on external links. Dialup and youtube don't make a good combo. At least it didn't when I was on dialup. Even on dsl, youtube still runs slow for me sometimes. Sometimes people are trying to keep their internet time down (I DO have to go to work in a few minutes) and just don't have the time to watch a video.
Not everyone is an A/C expert, and not everyone's AC is broken. I clicked because mine IS broken, but I've not looked at it yet.
Sometimes, posts just don't get a whole bunch of responses. No particular reason, it's just the way it is. There's been times I spent a LOOOONG time writing, editing, proofreading posts, and gotten no or only one reply. It's just the nature of posting on an internet forum.
Good luck with your A/C, let us know how you fix it.
