I don't think this is something that should be built-in to mIRC, but that doesn't discount the desirability of having the option to easily create/add one via a DLL.

I think that spelling in IRC is just as important as spelling in other mediums. Although I consider myself a fairly good speller, I often will find myself running to Firefox's Dictionary.com search-box to make sure I'm communicating effectively; I can imagine this being a great help to people who are just learning a language as well. So, it would be very useful to multiple types of people if mIRC made a spell-checking feature easier to implement.

Unfortunately, I doubt even facilitating such a feature is high in priority. For the record, though, Trillian has a plugin for spell-checking that is very useful; it also, of course, has the Wikipedia entry green underlines, which is a whole other feature entirely. smile
