This page specifies which newsgroups to replicate from a feed server. Because there can be many of them, newsgroups are specified by simplified regular expressions. The simplified expressions allow either a full newsgroup name containing alphabetic characters separated with a period ".", or a newsgroup name containing the characters ".*" at the end of the string, indicating that all sub-newsgroups should also be included.

For example, the expression alt.* would include all newsgroups that begin with alt, excluding the group alt, where the expression alt.binaries would only include the alt.binaries newsgroup. Negation can be used by putting an exclamation mark at the beginning of the string, for example, !alt.binaries.warez.*. If no groups are specified, then no groups are allowed in the feed.

Pattern matching runs from top to bottom until a match is found. If the matching pattern is not a negation, then the group is included in the feed. If the matching pattern is a negation, then the pattern is excluded from the feed. Matches other than the first are ignored. Because the list is unsorted, you must arrange the subscription list in a meaningful order.

Newsgroup
Provides a space to type the name of the newsgroup or a pattern to match.

Subscription List
The Subscription List displays a list of newsgroups in the order in which they will be processed by pattern matching.

• Click Include to add the text that you type in the Newsgroup box to the Subscription List. After you add a newsgroup, it will be replicated with the feed server.

• Click Exclude to add the text in the edit box to the list of newsgroups to exclude from the feed.

• To remove a newsgroup from the list, click the remove icon next to it.

• Click the move up icon to move the selected newsgroup up in the Subscription List. Newsgroups towards the top of the list are processed first by pattern matching.

• Click the move down icon to move the selected newsgroup down in the Subscription List. Newsgroups towards the bottom of the list are processed last by pattern matching.
