Hello @carpediem16 This is a great question and has been raised previously on the forum.
The forum remains a place for both sitters and owners, but we have some restrictions and I am happy to share why below 
The forum terms state that neither sitters nor owners can post sits or sit requests on the forum as the best place to find a sitter or sit is always via the main THS platform.
The exception to this is the last-minute-sit category for owners needing a sitter within 7 days. There is no sitters last-minute sit category as the forum mimics the function and processes of the main THS platform and on the THS platform, sitters have no option to advertise a sit. How it works is that sitters apply to available housesits.
We can not add functionality to the forum that is not part of THS or how THS works.
However, if one day THS added a function for sitters to be able to post sit dates/locations of where they would like to sit to the main platform then we will gladly add a last-minute sitter category to the forum as well.
It’s also worth knowing that the forum only has a small percentage of the whole THS network so it is unlikely that there would be a match between members when posting your sit requirements, especially with just 7 days to go!
It is much better to set up saved searches (especially on the app) so you are alerted to sits that become available for your desired location and dates.
I hope this explains things a bit more for you.
Maybe add a suggestion to this thread about adding a feature to the platform that allows sitters to advertise for sits.
Thank you!
