I guess you are saying about the problem, when you paste some text or include an image in the posts. Some cases, the text is shown out of the text area. This happens even in ELGG community posts.

Is this you are asking about? Actually I could not understand your problem.

no mate i wish to insert spreadsheets and increase the size of cells allowed which i thought i had done.. see next comment.

it seems that roughly speaking it can take 464 cells before i need to split it to another page

example spread sheets. first sheet needs alot more vertcally

example spread sheet 2. will need more horizontally as more players score goals hence the need for a horizontal scroll bar.

i thought this had done the trick.. but maybe i did it wrong(question mark)
