Link exchange sidebox and page-text customization

[moksha]

Hello,

I've created a new thread 'cause can't find much info on this.
I've recently activated the "links" sidebox for links exchange. It works fine but have noticed a few problems with the text definitions and with the popup help boxes on the submission and link pages:

1) Here: http://www.thequintessence.biz/index...e=links_submit

I found this line in my includes/languages/english/links_submit.php:

define('TEXT_MAIN', 'Please fill out the following form to submit your website.')

but the text doesn't appear on the page. Do you know why?
Then, on the same page, when clicking on the popup help link, the box that appears has a black background and no text in it (even if defined in my links_submit.php). Where can I fix this?

2) Here: http://www.thequintessence.biz/index...ain_page=links

I'd like to add an explanatory text at the top of the page. How can I do this?

3) Admin>extras>link categories. I've added a description to each of my categories but none of them appear when I click on the category links on my site. Why is this?

Sorry if I've listed so many problems, but thought it would be best to include them all in the same post to this forum seeing they are related.

Thanx for any help!
