We have made a group were the lower rated can challenge the higher rated and then we both analyse the game. Message me to send you invitation if you want(it's a small group for only few dedicated students).
Hey, I am interested in this group! I would love to play games against higher rated players, and I am serious about improvement as well. I would enjoy analyzing games and talking about my deficiencies and blunders in chess. Would you mind sending me an invite as well? Thanks!
And yes my end games do need work since sometimes I blunder a winning end game or even end up stalemating a checkmate. It does happen unfortunately.
), since I am rated similarly to both of you in real life, but I can safely say that, without experimenting, I would be still hovering around 600. Anyways, best of luck to both of you! 
I feel your pain mjharris77. I've been trying to get back to 1800 on Rapid for over a year, and just like you I don't feel as if I'm improving either. Every time I approach 1800 I lose several games in a row (or the site crashes and I lose points that way) and have to start the climb all over again. It's aggravating to say the least.
According to my stats I am in the top 3% of the site, but it sure doesn't feel like it. It's gotten to the point where I assume everyone is subtly using engines, as in some of my games that I've analyzed the analysis board says that my opponent didn't make a single mistake - it's hard to stay motivated when that happens! At one point I lost so much motivation to play online chess that I didn't come to this site for months.
