# Messages & Comments

### Chat vs Forum Posts

**Comments and messages work and display differently on Forum Posts and Chat.** In forum posts, comments are ordered from earliest to latest and replies are nested under the initial comments (comment thread). This layout is typical of forum post comments as seen on Reddit, X, and other forum-based platforms.

**With chat, messages are also ordered from earliest to latest but the chat window will show the latest messages first (scrolled to the latest).** Replies are quoted replies and do not nest under the initial message - they are displayed when the reply was made.

### Replies

**Users can reply to messages and comments.** Replies are limited to single-thread replies, meaning users can reply to an initial comment but not reply to a reply. When replies are made, push notifications are sent to the owners of the initial messages/comments.

### Mentions

**Users can use the common @ symbol to mention users within comments and chats.** When a user is mentioned they are notified via push notifications. Users available in the mention list are users that are: Owners, Moderators, and Contributors (A user that has at least made 1 comment/message).

### Reactions

**Users can react to comments and posts with a limited number of emoticons.** Reactions are limited for the reason of sentiment analysis which will be used in future analytics. Available reactions are:

1. 👍 Like / 👎 Dislike
2. 💖 Love
3. 😂 Funny / Laugh
4. 😢 Sad
5. 😮 Surprised
6. 😕 Worried
7. 😡 Angry

### Uploads

**Users can upload media limited 4 attachments per comment/message.** The maximum size per file is 5MB, and accepted files are images, video, audio, and pdf.

### Limits & Safeguards

**Safeguards have been put in place to mitigate comment/messaging abuse.** Along with the ability for users to flag comments/messages, additional controls have been put in place:

1. **Comments/Messages are limited** to 1024 characters.
2. **Strict text sanitisation** based on security standards on comments and messages.
3. **Posting is throttled** at a max rate of 10 comments/messages per 10min per user.
