It's called sarcasm. He did not mean to be payed.
What I think Andreas wanted to say is, that people who ask to be
guided - and that are lots of people lately - simply try to steal
other peoples time.
OMNeT++ is very well documented, especially the process of
implementing ones own simulation model or communication algorithm. And
the INET-Framework that usually will be the base of implementing a
communication protocoll is also quiet good documented. And there are
lots of implemented protocolls in there to learn from.
So start by reading through the manuals, try the tutorials, have a
look into the code. That's what gets you started, nothing else.
If you have special questions, look harder into the manual, code, etc.
And if you can still not answer your question, you can ask here. But
nobody has the time to "guide" anybody. We all have our lifes to
live...
