Some Tips.. About it..

1.You can use both read more.. and expnad collapse hack together also.Just use second tutorial and dont remove that read more line in red i exlained above and use expander.js script.

2.Its working in all browsers now as it has been fixed but can create problems sometimes if you are using so many scripts in your blog.

3.In the javascript codes you added at top there is a line like this slicePoint: 280.Now you can change that slice point from 100-1000 i.e upto from which % it should put your expand/collapse link or Read More.. link . Enjoy...This HAck

One More Important Tip :-- You can use any image Link instead of showing read more link also just In the codes above in red line written is read more..... just use embeded image link there and save it.
