#1 After you get that error, did you try clicking on post again?
Because that is what I have done in the past and my messsage went through.
#2 What add-ons if any are you using?
For example: NoScript

For example: limited to only http://forums.verizon.com/t5/Learn-Community-Blogs/ct-p/BlogsandIdeas

#1. yes. No change.
#3. no, as far as I know.
