His point is that people don't like all caps and are unlikely to help you if you use them constantly. You're much more likely to get help if you don't use all caps. Feel free to use them, but don't expect many people to choose to help you when you do. And, in some forums/channels/etc, the use of all caps can get you banned for repeated use. I'm not sure what the policy is here about that, but it's just fair warning for wherever you go.

The other main point made is to ask for help in the script's forum as *they* are the ones who know how their script works and how to fix problems that are caused *by* their script. People here know mIRC and scripting, but you aren't going to find a high percentage of people using Omenserv here. If you go to their forums, you'll find almost all of them using it. Therefore, you have a better chance of finding someone who can help you. Asking here's fine, but you may never find someone here who can help you. That is why, when I see someone ask about Invision in this forum, I direct them to our own forum for help. We're more likely to be able to help there than others can help here.

Beyond that, if you did cross post to multiple locations (I don't know if you did), that's almost always frowned on in forums because people end up replying to two or more different locations and trying to figure out what's going on in multile locations is difficult at best. It also results in people posting the same answers many times for no reason, which just wastes people's time. And if someone else comes along looking for help on the same issue, that person will have difficulty finding all of the replies if they aren't in on location.
As far as the opinion on the quality of that script, everyone's entitled to his or her own opinion. I've never used it, so I have no opinion of it.
