To create a new web:
1. **Create** a new web data directory under `twiki/data` and check the file permission of the directory.
- - Use a name consisting of characters `A..Z` , `a..z` but **_not_** in [[WikiNotation]].
+ - Use a name starting with characters `A..Z`, followed by `a..z` and/or `0..9` characters, but **_not_** a [[WikiWord]].
2. **Copy** all files from the `twiki/data/_default` directory to the new data directory, preserving the original files' owner, group and permissions (on Unix, use `cp -p`). The data files must be writable by the owner the CGI scripts are running on (usually, `nobody`).
- **_HINT:_** You can set permissions of `.txt` and `.txt,v` files to `-rw-rw-rw-` (666) and then edit the topic using your browser; RCS will restore the file permissions correctly when saving the topic.
3. **Add** the new web to the web list (visible in the upper right corner of each topic) by editing the site-level preferences, [[TWikiPreferences]]:
