Would it be possible to make the forum description field a textarea rather than just a text field?

My reason being, I need to add several lines of text to each forum description, and once saved it only shows a portion of my description (the rest being spluttered out underneath the text field).

The text description works on the forum, but everytime I edit that forum I have to re-add my lengthy description again otherwise it saves only the portion that fits in the limited size text field that currently exists.

Simple modification and would be a handy addition for me in particular, and others I'm sure.

Thanks!

PS: Oh and made a small donation too, great work guys!
