Surprisingly we all get along as well as we do.
Most all these things mentioned here are the very things people have complained about for years in all forms of communications.

As for CAPS-LOCKING. I have clients that leave the caps lock on all day because of their programs and apps that they work with every day. Their IT Dept. tells them to do this since 99% of what they enter needs to be in CAPS. In turn they email people with it still stuck on. Hey, it happens, so deal with it I guess. Luckily I know this and I give them a break.

As for not getting back to you... YES I hate that. I just received an email from another reseller similar to the one I work for. He was supposed to help me fix a product that his company sold us (and that we turned around and support for a local customer). He wouldn't get back to me after many emails asking for his help (after all he sold it to us, right?), yet I could see the read receipt, so I know he got them. (By the way - who hates people that use this feature in Outlook? - because... I use it). Anyway,
over a month later he replied to my last email and said he was sorry, he was very busy at work as things got crazy there. Yet he never answered my question - again. I guess he figure it was a dead issue after not hearing from me after a month or so. Not a good support practice.

People are people. We have to live with one another and with all their faults.

Now get back to work you people!
