If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
If you need to edit a post that's more than a week old, you can contact a moderator. When a wiki page is edited, the edits are logged and the page can be reverted if necessary. The forum, however, offers no such security. For this reason, editing is locked after 7 days to preserve post integrity. Please also keep in mind that reference materials should go on the wiki, not the forums.
