There hasn't been any changes significant enough to make them bad; After all, it's only been 3 versions (6.16 was released in July 2004. 6.17, 6.2 and 6.21 are the only releases since).
The event structures etc. for the protection you're looking at haven't changed since long before that.
How are you defining Out of Date? If a script works in mIRC, no matter what version of mIRC, then there's no need to update it.
If a script is incomplete, then you should post that in the comments section about the script. Most (if not all) scripting sites require a script to be tested before posting it on the site, and some require independent verification that a script works before it will be posted.
In regards to dialogs, at no point before this last post did you state that you wanted/needed a dialog.
Out of date meaning they dont seem to be coded like you guys do today and not complete meaning i cant get all i was looking for in the same script like i posted and sorry yes I wanted with dialog that i forgot to mention. Anyway no need to get mad bro just forget I asked for this one :P
