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.
Snoopy: if you go to the news section and then to the tiki bros. archives they tell you what to do for almost every problem, and you need to allow popups at pogo to be able to play, also rebooting and keeping your cache empty helps there a lot. it is a great site, and the new mahjong is fun. it's an addicting fun site.
