Just seen Rylan's rant. Oh dear. So much to unpick there. The irony about us being fed the narrative. Good grief.

So I built a thing for instructors to handle class bookings: classta.co ... my partner does trigger point pilates classes and tried a bunch of other class/event schedulers but found them difficult to use or not flexible enough. So I went and built another one.

So much at HMRC is broken. My tax account tells me I have an overdue payment. Which is due end of this month. Either it's broken or they are just trying to scare people.

New data on farms and inheritance tax: a third of farm estates over £1.5m aren’t farmers but wealthy people avoiding IHT by sinking money into farmland.
