Forum bugs and feature request

Something I have noticed is when you hover over someone's icon or name, it shows the number of posts someone has made, but that number is almost always incorrect. It seems someone's first post counts as 2 posts. See user here for latest example. 1 post but profile shows 2 posts. I often look at people's previous posts for context on the problem so this bug makes me go into someone's profile looking for previous posts when there aren't any. 

Another weird glitch I just noticed now while adding the above hyperlink is if you don't wait a second or two after adding the link, it will put the link where you have moved your cursor to and not the word you highlighted. Also, there seems to be some kind of screening of the code in the hyperlinks. For example, I copied and pasted a phone number, and it included the code to click to call the number. Wouldn't let me post with the link in the post. Gave me a error. Hade to copy and then paste as plain text.

Last, I would like to request to add a feature to expend all the posts in a conversation so you don't have to keep clicking "Show more" over and over again with long posts.
