Change #image-container and #note-container from IDs to classes. This is
necessary so that we can use one container element for both the image
container and the note container. This may break custom CSS and
userscripts.
* Refer to it as deactivating your account, not deleting your account.
* Update explanation to clarify what is and is not deleted.
* Warn that deactivation cannot be undone.
Reject email addresses that known to be undeliverable during signup.
Some users signup with invalid email addresses, which causes the welcome
email (which contains the email confirmation link) to bounce. Too many
bounces hurt our ability to send mail.
We check that an email address is undeliverable by checking if the
domain has a mail server and if the server returns an invalid address
error when attempting to send mail. This isn't foolproof since some
servers don't return an error if the address doesn't exist. If the
checks fail we know the address is bad, but if the checks pass that
doesn't guarantee the address is good. However, this is still good
enough to filter out bad addresses for popular providers like Gmail and
Microsoft that do return nonexistent address errors.
The address existence check requires being able to connect to mail
servers over port 25. This may fail if your network blocks port 25,
which many home ISPs and hosting providers do by default.
* Make the bans, ip bans, ip addresses, and user feedbacks pages all
link to one another in the secondary links.
* Add quick search bars to the secondary links on these pages.
Side effects:
* The data-current-user-is-voter <body> attribute has been removed.
* {{upvote:self}} no longer works. {{upvote:<name>}} should be used instead.
Fix discrepancy between index action and show action. The index
action allowed members to see name changes for undeleted users, but the
show action didn't.
In related tags, remove the (X) button next to artist urls for marking
them as inactive. This was broken because it didn't record the change
to the is_active flag in the artist history.
Also remove non-nullable and default options from migration. The column
didn't originally have these options so they shouldn't be added if the
migration is reverted.
