I can't merge threads anymore. The option is missing from the menu.
I'm in the threadlist, select the thread but the "merge threads" option is not there.
Tried with the default original style, same problem.
Aha! That was my mistake. Didn't use this option for a long time.
I thought I would have to click merge threads and then get the option to select to which thead it should be merged and paste the url.
This is better indeed.
