Just to note that Rebol 2 is below 1 MB. Depending on platform, Core is normally below 300K and View is around 600-800K - http://www.rebol.com/downloads.html
Unfortunately Rebol 3 (Ren/C branch) is a little beefier at this moment :( The non debug version is usually between 1.2 & 1.9 MB - http://metaeducation.s3.amazonaws.com/index.html
This Rebol 3 size will shrink. Currently there is development on build & extension process which will help. NB. There's been a big refactoring/redesign of the Rebol 3 interpreter in last couple of years so there maybe (still) some artefacts from many forks/merging of codebase that could also be shaken out.
I never understood stuff like writing "forgive spelling" or "sp?" when the correct spelling is a Google away.
Some folks might be on a mobile device with an interface that makes it difficult to switch to another window. Or perhaps they are offline when they're writing it. Or perhaps they have mobility / accessibility issues that makes switching a challenge. Those are off the top of my head.
To my mind, worrying about someone's spelling when I can understand them perfectly is one of those "life's too short" issues, speeking personaly.
There's also momentum. They want to go write a quick comment and type their thoughts as they come -- not stop and Google things.
