When giving someone advice or making suggestions, make sure things are stated in such a way that the don't read the same way as a demand. You can't read tone of voice very well so word choice is even more important.
Voicing suggestions as requests is even better.
Give people a chance to change and respond at their own pace. I have found that things with the convention take about a week. If they happen sooner that's great, they were probably already done. If nothing happens in more than a week then it's time to check again, and probably with more than one person. A week tends to be the time it takes someone to read an email or post, confer with their resources, and then find the time to reply properly. Not all of us are lucky enough to be able to hop onto the forums and converse during our work hours.

Finally, try and learn the art of interpretation. That is, read between the lines when a person says something or responds. Sometimes the person could be trying to make a suggestion to you without coming out and saying something specific, other times they might not want to be confrontational about something.
As an example, in our recent back and forth about the hotel map I was working on, you made your first set of suggestions and I responded. In your first response you came across as demanding and self righteous, it sounded like you were trying to boss me into following your instructions. My first reply was a polite way of telling you to back off and not use that tone of voice with me. As the conversation went on I had to be more blunt until you got the message.
I know that you're a smart guy and really know your stuff when it comes to computers, but bless your heart you've got to know when to bite your tongue and wait for a person to ask for your expertise.
