Yes it’s been a long time coming but today we’re thrilled to announce — PBwiki now comes with spell check!
To double check your spelling, click on the spell check icon in your toolbar (beside the plugin icon). All misspelled words will be underlined with a dotted red line. Right click on the word to view suggested spellings.
We love feedback, let us know what you think!
