FWIW, I think a 'forex' thread must have a tag to be started at the minute. To have an untangled thread you need to report the first post after it is started, and request it be removed and left untagged. At some point the techs will fix this bug. But for now there are more important things for them to do (like squeeze new ads into every conceivable little bit of free space on a page).
Cheers
