This took me few moments to find again.Gent -- I use Tapatalk occasionally when I'm on my Kindle Fire, but haven't seen that I could "like" posts. Sometimes apps work a little differently on a kindle than on other mobile devices. Or maybe I'm just oblivious .. won't be the first time, as DH can tell you.
KC -- So maybe do you remember where you changed this in the account settings? If so, would you take pity on me and tell me where to look?
It's tricky, but here is how to find it: click on the 'My Account' icon at the top of the page, then scroll down to 'Control Panel' and click on 'Edit Forum Options'. A page will then pop up that will let you edit your user options. Scroll all the way down that page to where it says, 'Profile Options'. The 6th option down will let you choose whether you want to be notified when your posts are liked or not. If you choose to edit anything, just click on the 'Submit' button at the bottom of the page when done.nor can I find in my account settings where I can turn this feature back on.
I had looked at the "Edit options" page via the Control Panel several times and obviously didn't see the settings that I was looking for. It's really confusing that there are two forms that look quite similar at the top, but are really quite different overall.
Anyways, thank you, KC and IL, for the help! You set me straight.
