Joining The PPL?

[StefEmery]

Hi Friends! I am currently not a member of the PPL but recall at the rally that this is an organization that I should be apart of to collect international royalties. Feeling a little skeptical when I read this part in the registration process under Rightsholders Agreements -
"To join as a recording rightsholder member, you must give PPL the exclusive UK public performance and broadcasting rights in your recordings, so that PPL can license those uses of your recordings on your behalf." Just want to make sure I'm not signing something that I am not fully understanding! Can anyone advise on this? Thanks!
