Evening. We're afraid this is not possible at the moment.
You can hide whole topics in Customise but that only hides them from Active Conversations; they will still display on last 15 minutes/last hour/last day.
It is on the Very Long List of Things Tech Are Going to Work On Soon. But we're afraid this list is very very long and, as this is more of a wouldn't-it-be-nice tweak than a oh-my-god-the-site's-fallen-over fix, it may be a while before it finds its way to the top of the list.
Thank you Ann. But that doesn't really help. I don't want to hide individual threads. I want to hide whole topics/sections. I want to know what threads have been active in the last 15 mins/hr/day, but i only want to search throught the topics that are of interest to me: say .... baking, camping, special needs, aibu, chat etc etc. I don't want to look in AN, PN, baby names, etc etc. So what can I do?
I think it's because the thread topics you want to hide will be hidden in active conversations (ie: www.mumsnet.com/Talk?call=ActiveConversations rather than last 15 mins etc? Could you try that link instead? On that link there is also a minus button on the right hand side of each thread if you want to hide individual threads.
I want to click on Last 15mins/hr/day, but only see the topics i want. I do not want to see / have to search through : Ante-natal baby names, post natal, etc etc. Is this possible? I don't just want to hide particular threads, I want to hide whole topics, whole sections. Can I do this?
Please could you tell me how to hide topics. I went onto customise, but could not do what I wanted. I admit that I am not very techy, so would apprecare an 'idiots guide' , on how to do what I want. I normally come onto MN and click Threads 'I'm on'. This is fine. Then I normally search by clicking either: Last 15 minutes, Last hour, last day. It is these 3 that I wish to hide topics on. I no longer wish to have search through .. say AN threads and the PN threads. Please can you tell me how to hide the topics i don't want to see on these 3 sections/searches.
