np, also if you want to use it to update your welcome message
in skin1/admin/main/languages.tpl
at the top of the page add
Code:
<script language="JavaScript1.2" defer>
editor_generate('var_value[txt_welcome]');
</script>
Then add a link to skin1/admin/menu.tpl
to edit the text directly.
it's advisable to only use this after you have set all your other language variables, as it will cause a javascript error when editing other variables, although it's harmless.
