Spell check

I'm afraid we have no way of knowing what platform a user will be using and have no way to implement that into the forum. This would be something that Freeforums itself needs to add as an option.

You may have to be responsible for your own spellchecking. If whatever platform you're using does not support in-browser spellcheck (although most do these days), you can always use a free website like this one that allows you to copy and paste text into their program that will automatically spellcheck things for you.
