I've been on other websites and they really perform well on smartphones. This one is good but could be better. This forum is an example of something that works excellent with a smartphone.

What I really like about is the posts are formatted for a smartphone. On this forum, I have to resize the window to make a post fit the screen. The above forum sizes it automatically. Its very readable.
Thank you!
