You interpreted that almost correctly. The meaning was that you should try to implement it yourself. If you can't, ask for it (and make sure to say you tried). If you can start it, but don't know how to finish it, ask for help. Finally, if you finish it on your own, post it up as your own work and people will offer suggestions, criticism, etc.
Posting an idea and not even trying to do it yourself (or searching to see if it's already been done), implies laziness. People around here don't like to see laziness, and will flame it mercilessly. Everyone's done it at some point. Call it..."forceful advice".
tl;dr version: Before posting an idea and asking other people to implement it for you, try it yourself. And for heaven's sake, use the search function.
Actually Ill have to disagree with the "implement yourself then suggest part". There is a way around it, Roanoke, in your case, you have asked something which was implemented and thought of many times before (hovelports, tremx nodeports, google's portal mod(which is going very-very nicely), and many-many threads and posts concerning the issue) and obviously you get flamed due to the reason "This newbie thinks he is a genius".
The best attempt of pushing your ideas through would be to get to know the game, and mainly get to know the community, earn the "respect" (or rather just show that you know something about the game) and then you can comment or just slip your ideas into the posts. (Optimus was the one to suggest to make the hovelports, and the only thing I did was to just implement them, since I liked the idea and found it interesting to code). Or even easier, discuss them on IRC channel.
Other than that, the only way to get a positive feedback is to either present already made code, or start asking specific questions which are going to help you to implement your idea.
In general, there aren't many coders around, most of them are either busy with RL, or already have project(s) on which they spend most of their trem time, and its very unlikely that someone will attempt to implement your idea, especially with 1.2 pending (for several <sarcasm>"years"</sarcasm> already)
