If you’re an author of professional documents or want to improve your writing, Grammarly can positively impact your grammar and spelling.

    I have enjoyed using most of the suggestions made in this great article but one of them is not quite as described: Office Tabs. When you go to the download page, everything seems to suggest that it is freeware and nothing during the download process indicates it’s anything but…until 30 days is up. It’s only a free trial and not freeware and I was careful to select the correct version. Not only is it misleading, it doesn’t uninstall completely which is inconvenient and annoying. While I did enjoy the functionality of the software and would have been willing to purchase it, I didn’t appreciate the underhanded and deceitful tactics and won’t ever use it or recommend it.

      Appreciate this warning Tenika and, like you, I will demonstrate my lack of appreciation of such tactics by not going there, despite the initial attraction
