Hi PassiveAggressiveQueen,
Thanks for asking - and sorry for the delay!
You can customise the Threads I'm On settings. If you're on the desktop site, click on the Talk:settings tab at the top of the page, then scroll down to the Talk Options.
You can then change the following:
Threads I'm On - days to check: (choose from 1 - 19)
Threads I'm On - sort method: (choose either Most recently active or My latest post)
Threads I'm On - show replies: (choose either Yes or No)
Hope that helps.
