Before You Start

  • Open any post editor (new post or reply).
  • Make sure you have posting permission in that channel.
  • Keep images ready in JPG, PNG, or WEBP format.

Step 1: Mention Members

  1. Type `@` followed by a username.
  2. Pick the right member from the suggestion list.
  3. Continue writing your post after the mention.

Step 2: Add Images

  1. Click the image button in the editor toolbar.
  2. Or drag and drop/paste an image into the editor.
  3. Use JPG, PNG, or WEBP files up to 5MB.

Step 3: Add a Caption

  1. After image upload, a caption line is added for you.
  2. Type a short caption so members understand the image context.
  3. Keep captions simple and descriptive.

Step 4: Paste a YouTube Link

  1. Paste a full YouTube URL into the post editor.
  2. In post editors, valid links are shown as video embeds automatically.
  3. In replies, YouTube links stay as regular links.

Step 5: Publish and Verify

  1. Publish your post or reply.
  2. Open the published content and check mentions, images, captions, and video output.

Troubleshooting

  • No mention suggestions: check spelling after `@` and try again.
  • Image upload blocked: use JPG/PNG/WEBP and keep file size under 5MB.
  • YouTube not embedding: paste a valid YouTube link and use a post editor (not reply).
  • Too many mentions: reduce mentions and submit again.

Expected Result

Your content is published with working mentions, uploaded images, readable captions, and YouTube embeds where supported.
