im thinking more like a very very bare bones version, no pictures, no fancy html where pages are like 10kb or even less, for lighting fast usage even on slow nets.
pg is lightning fast ! try using firefox , lite version isnt worth it on pcs since all of the recurring graphics are loaded just once anyways. try increasing the cache size in firefox if you still have problems.
lite version for forums is possible, but it will take sometime as these days I am busy in improving, upgrading the main-site code and layout etc..once I get it done..I will comes towards the forums lite version! till then be patience...
