I have been active on several forums lately and most of them do have an option e-mail subscription, but I want to have my inbox clean nowadays and topic updates really bring in a lot of bulk mail. Are RSS reader capable of monitoring topics for updates? I wish to be updated of about 15 vBulletin topics via pop-ups (not e-mail), e.g. this online and receive a pop-up when somebody replies to the topic I've subscribed to. If you require any additional information or know of a better place where to ask this, please let me know!
