oh I guess I should point out I did decide to become a paying member of this site and have been doing a lot of the tactics trainers which seems to help. I have tried chesstempo but the I really like the layout of chess.com. I also been using chessmaster GE! which seems to be a good learning tool.
At what point did you know you were improving your game!

It's a good question. I'd like to hear from those who broke through their first barrier of, let's say, 1400-1500 into that next level.

There are a couple of different places where improvement can show itself. I always thought I was a pretty good player but my performances OTB, especially in tournements, weren't very good. I had an old provisional rating from high school (2 games) when I started playing rated chess again in 2008.
I didn't do a ton of study the first year or so but began buying books and a year later joined the site here, getting a premium membership towards the end of that year when I saw all the features I could use.
However, I kept getting poor results in most of my games. I eventually realized I was moving too quickly and not really calculating very well or correctly. So I started taking more time and had a great tourney towards the end of 2011, and was able to keep up that performance.
From a rating standpoint, I've been pretty flat over the past year and a half. I'm finding myself again getting to positions were I move too quickly and not calculating very well, and have lost some games (and drew some) where I had decent advantages because of that.
I still have a lot of work and I hope I'm on the cusp of another jump
I am just curious if there was a defining moment where you knew your game started to drastictly improve? Over the last month or so i have been analysing my playing and it finally seems to be paying off. It almost feels like im playing a whole diffrent game than before. I am starting to see forks, pins, skewers a lot easier!
