use aspell (or similar) instead of iespell

[Guest Exiled]

The speckcheck option in the RTE of 2.1.x is very much welcomed, but AFAIK, iespell is limited to MS Internet Explorer.

Since you've done the hard part (primary integration), might I suggest that you consider a more compatible spell-checker? Aspell works in Linux and Win32, and I first heard about it from someone who was using it in MacOS X. I've read of it being used on many browsers and other apps (like the GAIM multinetwork chat program) in many (human) languages

I am not advocating for that program, specifically. I'm sure there are many other worthy freeware solutions for the well-explored and mature software feature. I simply think that spellcheck is too useful to be deliberately limited to a single browser, even the current market leader.
