Commenting on a thread or creating new one adds it to "threads I'm watching"

[antimatter]

It started yesterday .
Chrome Version 44.0.2403.130 (64-bit) on Mac

Yes, it started doing that to me too yesterday.

theres been a change to mumsnet (details were on another thread), go into customise above and untick the two boxes that say add to threads I'm wacthing.

Colours have all changed too!

Yes, it can be done via www.mumsnet.com/Talk?call=Preferences

However I still claim it is a bug (even if Developers or BA's decided it isn't)

Look in Site Stuff, a few long threads about it including the stickied one by MNHQ which will be at the top of your Active Threads.

Btw, it's all intentional

Haven't got time to read them hence this question.
