To access the important data of the forums, you must be active in each forum and especially in the leaks and database leaks section, send data and after sending the data and activity, data and important content will be opened and visible for you.
You will only see chat messages from people who are at or below your level.
More than 500,000 database leaks and millions of account leaks are waiting for you, so access and view with more activity.
Many important data are inactive and inaccessible for you, so open them with activity. (This will be done automatically)

Fibre and fiber are both correct, just that "fiber" is used more in America and TalkTalk seems to be an UK based ISP so it makes sense for them to spell it that way.
