So HF25 is set to go live on 30th June at 14.00 GMT I believe.
Give that it's a distinct possibility that the Chain won't be working for several hours, maybe half a day, maybe a whole day after said Fork, and also possible that it'll be a bit temperamental for several days after, I like to 'get ahead' with my posts and curation.
I tend to put out my 'last post' around six-eight hours before a HF to give people some time to read it, and to allow enough time for the Chain to settle down so I can still keep up my one post a day norm!
And I tend to deplete my VP more than usual in the hours leading up to the HF, given that any down time means you can't vote, so you may as well set yourself up so your account can recharge if you can't get into the system.
I also just leave financial transactions well alone for a day surrounding a Fork!
It's quite simple really, just about maximising your resources in case there is downtime.
Of course, IT MIGHT go smoothly!
