Well a lot of your complaints have been addressed and or fixed over the last several months. Look at some of the topics in Site Help and Site News and Comments to get your answers.
Here's a few for free. Go to "edit profile" click on "site options" and change the first drop down menu (the one for "sort posts") to Ascending. Now when you click on a topic it will show the first post first.
I found AkitaDog by going to the Forum page and clicking on view all users in the upper right and I typed his name in the search field. A link to his profile and a special button to PM him came up as a result to my search.
Keep poking around and click on things, you can't hurt it and can only get more familiar with the system. If all else fails and you can't figure it out, just ask instead of complain.
BTW, I'm just a dumb biker, without a computer degree, who loads trucks for a living and I figured it out.
