How do I split or merge topics?
In general, it's best to split threads that need to be split early. Otherwise, it can be hard to separate the discussions.
In cases where it's clear a topic thread needs to be split, and you have the permissions, feel free to do so.
Ask Mods to Check it Out
In cases you aren't sure if it makes sense to split or merge, or splitting a thread looks tricky, just flag the thread and a moderator will sort things out.
Do it yourself
All Sustainers (Discourse Trust-Level-4 people) can split and merge posts.
Step 1 - Send a direct message - Let those involved know you are splitting the thread and why you are doing it. This will encourage folks to help keep things tidy going forward. There is a canned reply you can use.

Click "select posts" >>
This will give you options to select which posts in the topic thread you want to separate out >>
Select all posts that apply, and select New Topic to split, or Existing Topic to merge >>
