You have published your first post! If you have a look at the top corner where it says how long ago you published it, you will see three little dots - click on them for a menu of options! All of them are pretty self explanatory, but a few tips:
Unfollow/Follow a post - you are keeping an eye on any activity on this post. You will get a little email to tell you if anyone comments or follows the post.
Edit post - Whoops! You made a mistake or left something out? No worries, just edit the post - don't forget to save your changes!
Share post - share your post or anyone else's post on another platform or via email.
Delete post - Je ne regrette rien... but if you then do regret the post, hit the delete button!
You will see those little dots on other posts too - usually offering you Follow Post (if you want to see what responses it gets!) and Share post.... If a post contravenes the terms of usage of the site (link at bottom of the page) then click Report Post and we'll look into it!
