@Marion Thank you for your feedback, I understand the concerns if you make a small typo etc, the great news is you have 30 mins after each post/comment to edit them, so there should still be time when you read it back after posting it.
I hope to reassure you further that if a post or comment is offensive and the user does not edit it in the 30 mins after posting then it will be dealt with as we always have done, in line with our posting terms. It is also likely to be flagged by other users, which we always appreciate 
Thank you for your suggestions about closing threads. We try and keep many of them open as new forum users or members new to housesitting might join and find them very relevant even months later, they might want to add to the conversation or share some new information, that could reopen the discussion around that specific topic. But we can certainly look at very old threads or if the topic is no longer relevant.
Just to let you know when a member posts we do have a pop-up that shows similar threads and asks if they would like to post on one of those topics rather than starting a new one about the same thing. We also have a pop-up when a member comments on an old thread letting them know that it is old and that are they sure that they really want to reopen the thread.
As the forum continues to grow we will reevaluate how best to use these features. Thank you for all of your suggestions so far
