It is not social media whee people post all sorts of drivel just get get some thumbs ups after their avitar.
It is a help forum where people come to find the answer to problems more than to express uninformed opinion.
Please leave that sort of rubbish for waste of space places like Faeces Book or What's up Doc.
If you really need to approve a post then there is :thumbsup: in the more emojies section along with :thumbdown: if you think a post is tosh.
Nothing to stop you doing a reply with one of them in if you really feel you have to.
However if you think a post deserves a :thumbdown: then your reasons would be good because this is a place for intelligent thinking people.
