How do i take over a thread?

[MRSTJ]

As the title says how do i take over a thread? The thread im looking to take over is the slimming world one in the dieting section as the orignal op no longer can keep running it?

PM me the link to the thread, and have the OP message me as well saying that it's fine to take over and I'll change the thread owner to you
