Forum reply box text colour

Hello, I have recently purchased GameAddict and must say I really love the theme!

I have hunted around for a solution to this, and the solution is probably so simple that I am missing it…but I would like to change the colour of the text in the forum reply box? At present it is a very light grey and some users are finding it difficult to read/edit.

I originally inspected the element in Chrome and this led me to change main.css lines 11 and 15. Whilst this worked in Chrome’s inspected page, when I uploaded the modified file it did not change. So this is getting overridden somewhere.

I had changed some entries in both bbpress.css and buddypress.css but to no avail and so reverted them back to their original states. What css file should I be looking at changing?

Any help would be appreciated, thank you.
