I just want my form to give the options A, B, and Other___ without any changes. With this add-on, anytime someone submits a response under Other, it automatically gets added to the form as a new option in the list. Please give us a way to turn this feature off.

Great addon....But please! please!! please!!! Can you provide a way to "TURN OFF" the feature that updates the options list with whatever a user writes. Because a rogue user can write anything crazy... and that 'thing' automatically reflects in the survey that other participants will now see. Thanks.

I wish I had a add-on to change the text "other" to 'Comments", and to be added to the end of each item inside a question.

crikey, that was easy! no code needed and works seamlessly into the native setup. Does everything you'd hope with no bugs: a time lag of less than 2 seconds to feed it into the form, 'submit another response' includes the new option - and - even the user using the browser backpage shows updated form! Thanks devs!

DO NOT USE unless you are OK with what someone types under "other" being added to your form. It retains what is typed, adds it to the form, and it appears to the next person completing the form as an answer to choose.

It's very good tool to use if you trust the people that are answering your form, I just wish we had a add-on to change the text "other" to something else, like "self describe" or "if yes, which one".

I cannot use this add on for checkboxes because the checkbox does not offer the "other" option. It only allows me to "add column". It worked great for multiple choice but not what I needed it for.
