Oof that is pain. I have started to just move to a local text editor when i realize the comment is getting long.

Yeah, I wish there was a way to delete a post with out deleting it to preserve comments.

Maybe an "abandon" feature. It removes your user name from public view and does a simple find and replace to remove your name in the comments. The post can live on, but now you have nothing to do with it. The user would have a "abandoned post" counter, this so we know if a user is constantly abandoning posts and can block them. Or put a hard cap, more than 2 a month = banned from posting until mod appeal. Posts with 0 comments face no penalty and are deleted.

Someone still needs to be able reference to the original poster for modding and blocking purposes.
