Could you please tell us your thoughts on this subject as we are having controversy over what is a post to a forum vs. a post to a blog. Since the posting guidelines are the same for both and are open to interpretation it makes it difficult to distinguish between the two.
To me "tips and success stories" - "tips and failure stories" - "suggestions" means: share your successes, share your failures, share what worked for you pertaining to the subject of that forum you are posting in.
I think if you have personal problems aside from the topic of the forum and wish to discuss those problems they should be posted to a forum that is the subject of said problem you wish to discuss, or post it to a blog and let people reply to the blog.
Others interpret the guidelines completely different than I do.
