Obviously any mIRC user trusts mIRC to not contain malware. There's no reason to extend that trust to one of the few closed-source mIRC addons available. Maybe some people use it and are able to check that it doesn't do anything sinister, but the vast majority of mIRC users probably don't have the capability to check thoroughly and many wouldn't be willing to take a chance. Nor should they have to.
There are good sites/apps that will check things like this. Just as one example, SiteAdvisor from McAfee gives you a browser plugin that tells you about the site. If you look at the site details, you can see information on the downloads they offer and whether or not any contain viruses/adware/spyware/etc. Some are free, other cost money. Most are easy to use.
I'm not sure of your point on your second paragraph. Are you saying that because there's an addon available, no matter how poor or counter-intuitive it is to use, people who want this feature should just use it and not expect mIRC to add this feature? I don't really want to respond to that unless I'm sure that is what you mean, but lets just say that would be a very backwards way of looking at the world in general.
No, that's not what I meant. People have said in this thread and other threads on the subject that using that addon for audio/video is difficult, so no one wants to use it. I may be harsh in saying this, but if people REALLY want something, they will take the time to learn to do it. If they don't want to learn to do it, then they don't really want it. They may *like* to have it, but they don't really *want* it, or they would learn to use what is available. That may be a harsh statement, but it's true. If you really want something, you'll do what is necessary to have it (within reason).
I did mention that I don't care if it's added or not. I'm not against it being added. I just don't see the need to compete with IM. Just because IM has it doesn't mean that IRC has to have it. And vice versa.
I personally could care less if it's included. I have no need to see a dozen or more people's faces on my screen in order to talk to them, or hear that many voices. And if I really want to just do that with one person at a time, then what's wrong with IM? I use both. IM makes for quick messaging of people I know and I don't have to teach anyone about IRC or explain what server and channel I am in. It's useful for that. And because I use Trillian, I don't have to have multiple IM clients running at the same time to talk to different people. Nice and easy. On the other hand, I have mIRC for talking with a LOT of people at once, playing trivia, playing various other games, writing scripts for people, and having a good time. For me, IM is for chatting only... IRC is where I have fun with people online (other than playing online games, of course). mIRC has more value to me for that reason.
I don't need all those IM things included in mIRC. If enough want them and Khaled agrees, then we'll see them. He knows people want those items and he will decide, in the end, to add them or not to add them. Having dozens of threads really won't change his mind much. It's similar to the whole emoticon thing... it's been beaten to death so many times that he *definitely* knows people want it and if he wants to add it, he will. Rehashing it over and over won't change anything.
