This will flag comments for moderators to take action.
If you take a look at the bottom of each WEbook page (in the footer bar), you will be able to see the number of members who have been active within the last 24 hours. This is calculated based on the number of people who have commented, submitted some writing, or generally made an interactive action here on WEbook during the previous 24hours.
Like thepurplebug says, there are people here! Many people operate within closed groups, so our advice is always to jump in with two feet - find some writing that you like, send the author a message - begin the interaction, and before you know it you'll be involved in more things here on WEbook than you ever thought possible!
