I’ve changed the default notification setting to 
(“watching”) for the Law and practice and Miscellaneous categories.
If you are receiving notifications by email, you’ll start to receive an email for each forum post, not just the first post in a topic. You can reply to a post by email or by visiting the forum.
You can return back to the old setting by going to the relevant category and selecting 
(“watching first post”).
From now on the default will be to receive a notification for the first post in each topic, instead of every post, in the Law and practice and Miscellaneous categories. This is the (“watching first post”) setting.
You can choose to continue receiving notifications for every post by going to the relevant category page and choosing the (“watching”) setting.
Alternatives include watching individual topics which particularly interest you (by choosing the setting on the relevant topic pages) or turning off emails entirely (on your preferences page) and just visiting the site to read topics.
The reason for the change is that there are quite a lot of posts these days – I don’t want you to feel inundated with emails, and in any event it’s getting expensive to send them.
