I'm still getting used to Messenger Plus, so I'm sorry if I seem really daft about this whole extension.

Does Messenger Plus have a spell checker? It would be really nice if it worked similarly to Microsoft Word/Open Office Writer, where it underlines the misspelt word, and allows you right click it to see a list of possible corrections.

If such a thing exists, could you please tell me how I would get it to work?

Thanks very much!
