Please keep things positive. Best advise I believe is to try out different sites. Find what works well for you. If you don't like it, don't go back and try another site. Nothing says you only have to play on 1 site. At one time, I played on about 6 different turn-based game sites.
Ketchup: Do you remember chessed.com? It was the first online site where I played chess, or any online game. I do not even know how many years have passed since it died. I have been on BK for too long, I guess...
My first two attempts were rejected - once by a mod accidentally. The third was accepted but I added several ! at the end in hopes that help my post stick and because I was ticked off. My post "for the memories" was originally following the word "thanks". By the time it was accepted it was no longer in context and deemed nonsense and removed.
They also asked me to drop out of a championship tourney because I resigned my games in the last edition after I was eliminated from advancement. They find it unsavory (my word-I don't recall their exact words)
