FastComments Default Avatars Using Gravatar

What's an Avatar?

An avatar is the profile icon associated with every account and shown next to every comment.

What's Gravatar?

Gravatar brands themselves as "A Globally Recognized Avatar". It's a service where you can define an avatar for a given email. Any products you sign-up to using that email can then use that avatar. This removes a step for people signing up to FastComments since their avatar is setup automatically.

So what's the change?

FastComments will now pull default avatars from Gravatar. You or or users don't have to do anything to get this feature.

If your existing users have already defined their own avatar - no worries - we aren't going to overwrite their custom avatars. Also, users can still overwrite the Gravatar avatar in FastComments.

FastComments Gets Localized

Localization is no small step - and it's arrived at FastComments. The embeddable comment widget is now fully localized in English (en-us), Spanish (es-es), and French (fr-fr).

You'll notice that we haven't slowed down, either. Generally when most applications add localization support the bloat starts to set in. In our case the client-side script has actually decreased in size as we've done some housekeeping and other optimizations at the same time.

If you'd like FastComments translated in your language, or you've spotted a translation issue, let us know.

How to Disable Image Uploads In Your Comments

Mon Feb 03 2020 -

Configure How Long to Keep Unverified Comments

By default FastComments will keep your unverified comments for three days.

What does "unverified" mean?

When a user comments and leaves their email FastComments will send them an email asking them to verify their comment. This helps fight spam, and highlights the comments that their authors really want shown.

If you enable Anonymous Commenting they won't even have to leave their email!

But now you can configure how long to keep these comments - maybe you don't even want to automatically remove them! This is all configurable ia Moderate Comments -> Edit Moderation Settings

Mon Feb 03 2020 -

Threaded Pagination Comes to FastComments

FastComments now supports pagination without collapsing content! Also, if you want to read a long thread quickly FastComments has a "Load All Comments" button on long threads (like here).

This means that if you have hundreds of replies on a page we aren't going to bog down your site by loading them all up at once. One the user scrolls down to your comment section, and reads past the 30 comments we load initially, they can click "Show Next 30 Comments" to quickly load the next set and continue reading.

It's also well optimized, as usual. If you're into that kind of thing read about it on our engineering blog.

This requires no additional setup from you! Existing customers will get this feature. Enjoy FastComments.

Sat Feb 01 2020 -

How to Allow Anonymous Comments With FastComments

By default FastComments requires an email to comment if you are not logged in. We use this email to automatically create an account for the user and let them verify their comment. In order to allow anonymous commenting you just have to create a customization rule. Define the domain, and optionally page, that you want to allow anonymous commenting on.

Migrating From Commento To FastComments

Commento doesn't give us full URLs. What they provide is just the domain name that a comment thread belongs to - like "". This means that the FastComments importer has to assume what the protocol is, and it defaults to https. If you run the import and are not seeing your data you may want to check that your site is properly secured.
