From July 16th, 2020 to May 22nd, 2021, 100% user give 5-star rating. for BBOalert chrome extension.
I've been using BBOalert for a couple of months. I really, really like it. It allows me to automate most alerts and frees me to focus on the game. The best part is that the developer is available to help and/or respond to your suggestions. Stan's the man!!
This is excellent for people who play a relay system. If you have a system fully documented via Full Disclosure, you can use BBOAlert to provide your opponents with full explanations of all your relay sequences, saving endless typing. Also ideal for bidding practice and learning relay.
This is a wonderful extension and highly recommended.
