The Celigo Connective community is built on the Discourse platform. If you haven’t used it, here are a few quick tips and tricks to get you started:
Searching
One of the best ways to get started is to use the Search bar, accessible on the home page or via the magnifying glass in the upper right of every page.
Reading
Selecting a title from the topic list will always take you to your last read post in the topic. To enter at the top or bottom instead, select the Replies count or last Activity date.
Topics above the light red line are new or updated since your last visit. If you have read all the way to the end of a topic, its title will be light grey instead of black.
Replying
Press any 
Reply button to open the editor panel at the bottom of your browser. Continue reading (and even navigate to different topics) while you compose your reply; minimize the editor for more room. Drafts will automatically be saved as you write.
Quoting
To insert a quote, select the text you wish to quote, then press the Quote button that pops up. Repeat for multiple quotes.
Mentioning
To notify someone about your reply, mention their name. Type @ to begin selecting a username.
Emoji
To use standard Emoji, just type : to match by name, or traditional smileys 
Oneboxes
To generate a summary for a link, paste it on a line by itself. To start a topic with a link, paste the link into the title field.
Formatting
Your reply can be formatted using simple HTML, BBCode, or Markdown:
This is <b>bold</b>.
This is [b]bold[/b].
This is **bold**.

Actions
There are action buttons at the bottom of each post:
To let someone know that you enjoyed and appreciated their post, use the like button.
Grab a copy-pasteable link to any reply or topic via the link button.
Use the … button to reveal more actions. Flag to privately let the author, or the site staff, know about a problem. Bookmark to find this post later on your profile page.
Notifications
When someone is talking directly to you -- by replying to you, quoting your post, mentioning your @username, or even linking to your post, a number will immediately appear over your profile picture at the top right. Select it to access your notifications.
Don't worry about missing a reply – you'll be emailed any notifications that arrive when you are away.
Preferences
All topics less than two days old are considered new, and will show a new indicator (blue dot).
Any topic you've actively participated in -- by creating it, replying to it, or reading it for an extended period -- will be automatically tracked on your behalf, and will show an unread post count indicator.
You can change your notification level for any topic via the notification control at the bottom, and right hand side, of each topic. (Notification level can also be set per category, look for the notification control [bell] on the upper right of each category page.)
To change any of these defaults, including the choice of a dark theme, visit your user preferences, accessible via your Profile circle in the upper right.
