Hi,
Don't worry about that too much, jrv is just frustrated with the web interface here. He may complain about it, but that doesn't stop him from being the top poster every single week.
While he has some points about the overall usability of the site (especially since the massive UX change in 2013 and the reassignment of the previous forum staff), I don't run into the code posting issues as often as he does. That certainly seems to be his
biggest complaint from what I've seen.
A good number of MSFT forums have made the move over to StackOverflow and given up on TechNet/MSDN, so the trend has already started. We'll see how much effort MSFT actually wants to put into these forums going forward.
That said, there's nothing stopping you from continuing to post here. The community is still pretty active, at least in the forums I frequent.
