By clicking, you will open the pop-up window where one can type the name of the link:

For your convenience, any links inserted into a message are instantly recognized and become active, meaning you can click on them to automatically navigate to the specified address. Any URL is considered a link; however, certain conditions have to be met:

1. Any text beginning with http:// or https:// will be treated as a link.

2. When the protocol is not specified, URL links are automatically recognized if the top-level domain is included in the list of allowed domains. For instance, example.com is recognized, whereas example.some is not.

3. A link should not end with the following characters: :\ ? # [ ] @ ! $ & ' ( ) * + , ; . { } ^, as they won't be included in the link. This rule does not affect the characters - _ ~ % =. If an allowed character is followed by a prohibited one, the link will end at the last allowed character, ignoring everything that follows.

4. If the link ends not with a single closing parenthesis, but with one that matches an opening parenthesis, such a parenthesis will be taken into account.

Examples of correctly formatted links:

• http://example

• http://example.example

• example.com

• https://example.net/blog

• video.example.com/#anchor
