I know it's gonna take time to find everything on this site but it will get easier.

I wanted to point out that you have many options to search for post. It's all in one place with two clicks! Scroll to the top left and click Quick Links to get this drop down menu

Another way to look for new topics is the icon on the left next to the title.
The little star means you commented
The rose means no unread topics
A red icon means new posts
and a black icon means no unread replies

You can also use the red page icon for unread posts and the paperclip indicates attachments

How do I post to an existing topic? For example: Introductions. How do I post to the Introductions forum?

Click Home, Introductions, the new topic tab is at the top left click that to start a new thread or click on any other thread to respond.

I must be missing something obvious but cannot figure out how to thank someone for a post. I thought I saw something about it somewhere but I haven't found it again!!! Otherwise THANKS for a great site. It is really fun to come here often and see all the changes and additions!

It's at the top of the tool bar but it's a thumbs up icon!! Confusing I know but it's what we have for now and Thanks, it's a work in progress and we'll get there eventually.
