I have submitted posts, blogs, etc. on various forums and sites where editors/hosts/admins have changed my titles on occasion. While I generally had reasons for the titles I used, I had no problem with the changes. I'm not saying what I think anyone else should do, but I do not have a problem with having a forum host alter the title of my thread, move it to a more appropriate sub forum, or even lock it as they see fit without notifying me first. I can also understand why someone else might feel differently.
To me, this is a dynamic community where I am only one participant in a larger (rather noisy) discussion. If I have something I really want to say without any external filtering or editing, I'll say it on my blog. That's just me, however. YMMV.
I enjoy following Spacey's threads on guitar building even though I have absolutely no skills (or comprehension) in that area. It's good to see an artist at work. I hope we get to see more.
