This is a constant issue but seems particularly bad at the moment.
Posters putting replies on threads without rtft.
Now I can understand not reading every post if it's a very long thread (though it's not compulsory to reply).
But to not even read the OP'S posts - which usually gives you an indication of what's been said and certainly gives all the information other posters are replying using - is SO ARROGANT!
Some I've read recently the poster clearly hasn't even read the VERY FIRST POST properly and missed crucial info.
Seriously SO ANNOYING!
Also I can't remember how to do it but I'm sure some wise mner will and can post it - but you can set it so that OPS posts are highlighted too so you can scan through and find their posts and read them BEFORE you make a suggestion that's already been rejected & the reason or other similarly daft comment.
It's making threads very repetitive to read.
